Update Library Links in a Subsystem
In this example, myModel
contains a single
subsystem, which is a library link. After the model was last opened, a
Gain block was added to the corresponding subsystem in the
library.
Open the model. Use find_system
with
'FollowLinks'
set to 'off'
. The
command does not follow the library links into the subsystem and returns
only the subsystem at the top level.
open_system('myModel') find_system(bdroot,'LookUnderMasks','on','FollowLinks', 'off')
ans = 'myModel' 'myModel/Subsystem'
Use find_system
with 'FollowLinks'
set to 'on'
. find_system
updates the
library links and returns the block in the subsystem.
find_system(bdroot,'LookUnderMasks','on','FollowLinks','on')
Updating Link: myModel/Subsystem/Gain Updating Link: myModel/Subsystem/Gain ans = 'myModel' 'myModel/Subsystem' 'myModel/Subsystem/Gain'
Return Values as Handles
Provide the system to find_system
as a handle. Search for block dialog box parameters with a value of 0
. If you make multiple calls to get_param
for the same block, then using the block handle is more efficient than specifying the full block path as a character vector.
load_system('vdp'); sys = get_param('vdp','Handle'); find_system(sys,'BlockDialogParams','0')

function with the MatchFilter
option to operate on
all types of variant blocks.
MatchFilter
— Option to match and filter elements in search
function handle
Option to match and filter elements such as blocks, system, lines,
ports, and annotations in a search, specified as function handle. Use
MatchFilter
to determine whether elements
should be included or skipped in a search.
The argument:
Allows you to filter elements with custom filter functions
Avoids processing elements when filters do not match
Applies complex filters on blocks, lines, or annotations, to filter the results internally
The named function must be defined within a MATLAB program file. The function takes the handle of the element as input and returns two outputs.
function [match, prune] = func(element)
The input
element
is the handle of the block being processed.The first output,
match
, is a logical value. Iffalse
, search skips the element.The second output,
prune
, is an optional logical value that only applies whenelement
is a subsystem. The default value isfalse
. If this value is set totrue
, the entire subsystem is omitted from the search.
Example: Use MatchFilter
to find all non
Inport and Outport blocks in a model
using your own defined filter function,
nonInOutBlocks
.
function match = nonInOutBlocks(handle) match = true; if strcmp(get_param(handle, 'Type'), 'block') blockType = get_param(handle, 'BlockType'); if strcmp(blockType, 'Inport') || ... strcmp(blockType, 'Outport') match = false; end end end
load_system('vdp'); blks = find_system('vdp', 'MatchFilter', @nonInOutBlocks)
Variants: Simulink® provides these built-in match filter functions to find variant blocks that are active in simulation or part of the generated code.
Simulink.match.activeVariants
— Filter function to find blocks that are active in simulation after model compilation.Simulink.match.codeCompileVariants
— Filter function to find blocks that are part of generated code after model compilation.Simulink.match.allVariants
— Filter function to find all blocks irrespective of whether the block is active or inactive due to variants.Simulink.match.variantAssemblySubsystems
— Filter function to find all the Variant Assembly Subsystem blocks.
Note
To get correct results, you must compile the
model before using
Simulink.match.activeVariants
and
Simulink.match.codeCompileVariants
filters.
If the model is not compiled, these filters return all blocks in the
model.
For an example that compares the pre-compile and post-compile time results for these filters, see Use find_system with Built-In MatchFilter Options for Variant Blocks.
Example: Use the Simulink.match.activeVariants
filter to find active variants in a model.
openExample('simulink_variants/BuiltInMatchFiltersWithfindsystemForVariantBlocksExample'); model='sldemo_variant_subsystems'; load_system(model); assignin('base','VSS_MODE',2); set_param(model, 'SimulationCommand', 'update'); activeBlks = find_system(model, 'MatchFilter', @Simulink.match.activeVariants);
Example: Use the Simulink.match.codeCompileVariants
filter to find variant choices that are part of the generated C
code.
openExample('simulink_variants/BuiltInMatchFiltersWithfindsystemForVariantBlocksExample'); load_system('sldemo_variant_subsystems'); assignin('base','VSS_MODE',2); sldemo_variant_subsystems([], [], [], 'compileForCodegen'); activeBlks= find_system('sldemo_variant_subsystems', 'MatchFilter', @Simulink.match.codeCompileVariants); sldemo_variant_subsystems([], [], [], 'term');
Example: Use the Simulink.match.allVariants()
filter to find all blocks in a model.
find_system('sldemo_variant_subsystems', 'MatchFilter', @Simulink.match.allVariants);
Example: Use the
Simulink.match.variantAssemblySubsystems()
filter
to find all the Variant Assembly Subsystem blocks in a
model.
openExample('simulink_variants/ChoicesMaskVariantAssemblySubsystemMaskParamObjectExample'); load_system('slexVariantAssemblySubsystemWithMask') find_system('slexVariantAssemblySubsystemWithMask', 'MatchFilter', @Simulink.match.variantAssemblySubsystems)
Output Arguments

Matching objects found, returned as:
A cell array of path names if you specified
System
as a path name or cell array of path names, or if you did not specify a systemA vector of handles if you specified
System
as a handle or vector of handles
Version History
Introduced before R2006aR2022b: Warnings for removal of Variants
argument
As part of the removal of the Variants
argument in a future
release, these warnings have been introduced:
When you use the
find_system
function without theVariants
argument, the function generates a warning if it skips the inactive choice of a Variant Subsystem block during the search.Consider a model with a Variant Subsystem block that has two variant choices,
Linear Controller
andNonlinear Controller
. TheNonlinear Controller
block is the active choice.This command skips the inactive
Linear Controller
block and generates a warning.blocks = find_system('sldemo_variant_subsystems/Controller')
Warning: Using find_system without the 'Variants' argument skips inactive Variant Subsystem blocks in the search. This behavior will change in a future release to look at all choices of the Variant Subsystem. To find blocks that are active in simulation or code generation, compile the model and use the built-in variant filters with the 'MatchFilter' option. blocks = 12×1 cell array {'sldemo_variant_subsystems/Controller' } {'sldemo_variant_subsystems/Controller/sensor1' } {'sldemo_variant_subsystems/Controller/sensor2' } {'sldemo_variant_subsystems/Controller/sensor3' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller/sensor1' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller/sensor2' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller/sensor3' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller/1-D Lookup Table'} {'sldemo_variant_subsystems/Controller/Nonlinear Controller/Add' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller/Out1' } {'sldemo_variant_subsystems/Controller/Out1' }
When you use the
Variants
argument with its value set to'AllVariants'
, the function generates a warning.blocks = find_system('sldemo_variant_subsystems/Controller','Variants','AllVariants')
Warning: 'Variants' will be removed. Instead of using 'Variants' with value set to 'AllVariants', use 'MatchFilter' with value set to @Simulink.match.allVariants. blocks = 19×1 cell array {'sldemo_variant_subsystems/Controller' } {'sldemo_variant_subsystems/Controller/sensor1' } {'sldemo_variant_subsystems/Controller/sensor2' } {'sldemo_variant_subsystems/Controller/sensor3' } {'sldemo_variant_subsystems/Controller/Linear Controller' } {'sldemo_variant_subsystems/Controller/Linear Controller/sensor1' } {'sldemo_variant_subsystems/Controller/Linear Controller/sensor2' } {'sldemo_variant_subsystems/Controller/Linear Controller/sensor3' } {'sldemo_variant_subsystems/Controller/Linear Controller/Add' } {'sldemo_variant_subsystems/Controller/Linear Controller/Discrete↵Transfer Fcn'} {'sldemo_variant_subsystems/Controller/Linear Controller/Out1' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller/sensor1' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller/sensor2' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller/sensor3' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller/1-D Lookup Table' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller/Add' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller/Out1' } {'sldemo_variant_subsystems/Controller/Out1' }
R2022a: New built-in match filter to find all variant blocks
You can use the built-in match filter,
Simulink.match.allVariants
, to find all the blocks in a
variant model regardless of whether the block is active or inactive due to variants.
This filter is the recommended replacement for the AllVariants
option.
To be removed | Recommended Replacement |
---|---|
find_system(model,'Variants', ... 'AllVariants'); |
find_system(model,'MatchFilter', ... @Simulink.match.allVariants); |
R2021a: Default behavior has changed for Variants
and MatchFilter
arguments in model with variant blocks
Variants
: When you use thefind_system
function without specifying theVariants
argument, the function currently includes only the active variant choice for Variant Subsystem blocks in the search by default.For other variant blocks such as Variant Source, Variant Sink, or Variant Subsystem blocks with the Propagate conditions outside of variant subsystem parameter set to
on
, the function includes all choices in the search.Consider a model with a Variant Subsystem that has two variant choices,
Linear Controller
andNonlinear Controller
.This command returns only the active Add blocks in the model.
add_blocks = find_system('sldemo_variant_subsystems/Controller',... 'BlockType','Sum')
add_blocks = 1×1 cell array {'sldemo_variant_subsystems/Controller/Nonlinear Controller/Add'}
MatchFilter
: When you use thefind_system
function with theMatchFilter
argument, the function applies the filters on the active and inactive variant choices by default.Consider a model with a Variant Subsystem that has two variant choices,
Linear Controller
andNonlinear Controller
. The filter functionfindAddBlocks
finds all the Add blocks in the model.function match = findAddBlocks(handle) match = strcmp(get_param(handle, 'Type'), 'block') &&... strcmp(get_param(handle, 'BlockType'), 'Sum'); end
This command returns the active and inactive Add blocks in the model.
add_blocks = find_system('sldemo_variant_subsystems','MatchFilter',... @findAddBlocks)
add_blocks = 2×1 cell array {'sldemo_variant_subsystems/Controller/Linear Controller/Add' } {'sldemo_variant_subsystems/Controller/Nonlinear Controller/Add'}
R2021a: Variants
argument will be removed
The Variants
argument will be removed from
find_system
in a future release. Function calls that use
the Variants
argument continue to work with a warning.
Using the find_system
function with the
Variants
argument produces inconsistent search results.
The find_system
function is an edit-time operation, but to
determine whether a block is active in a model with all types of variant blocks, you
need to compile the model.
To find variant blocks that are active during simulation or code generation,
compile the model and use the
find_system
function with the
MatchFilter
argument.
This table lists the recommended replacement for different values of the
Variants
argument.
To Be Removed | Recommended Replacement |
---|---|
find_system(model,'Variants', ... 'ActiveVariants'); |
set_param(model,'SimulationCommand','update'); find_system(model,'MatchFilter', ... @Simulink.match.activeVariants); |
find_system(model,'Variants', ... 'ActivePlusCodeVariants'); |
model([], [], [], 'compileForCodegen'); activeBlks= find_system(model,'MatchFilter', ... @Simulink.match.codeCompileVariants); model([], [], [], 'term'); |
When you use the find_system
function, you cannot specify
both of the MatchFilter
and Variants
arguments.
This command produces an error.
find_system(bdroot,'MatchFilter',@Simulink.match.activeVariants,... 'Variants','ActiveVariants');
R2020b: Filter elements during search with MatchFilter
To match and filter model elements during a search, you can define a custom filter
function and pass the function handle as value to the
MatchFilter
name-value argument.
To find variant blocks that are active in a simulation or part of the generated
code, you can use the built-in match filter functions,
Simulink.match.activeVariants
,
Simulink.match.codeCompileVariants
, and
Simulink.match.allVariants
, after compiling the model.
