EMX array types identifier format

Customize generated identifiers for emxArray types

Model Configuration Pane: Code Generation / Identifiers

Description

Customize generated identifiers for emxArray (embeddable mxArray) types. The code generator produces emxArray types for variable-size arrays that use dynamically allocated memory. This parameter applies to MATLAB^® code in a MATLAB Function block, a Stateflow^® chart, or a System object™ associated with a MATLAB System block. This parameter does not apply to:

Input or output signals
Parameters
Global variables
Discrete state properties of System objects associated with a MATLAB System block

Dependencies

This parameter:

Appears only for ERT-based targets.
Requires an Embedded Coder^® when generating code.

Settings

emxArray_$M$N | string

Enter a macro that specifies whether, and in what order, certain text is to be included in the generated identifier. The macro can include a combination of the following format tokens.

Token Description

Token	Description
`$M`	Insert name-mangling text if required to avoid naming collisions. Required.
`$N`	Insert type name. For example, `real_T`
`$R`	Insert root model name into identifier, replacing unsupported characters with the underscore (_) character. Required for model referencing.

$M

Insert name-mangling text if required to avoid naming collisions.

Required.

$N

Insert type name. For example, real_T

$R

Insert root model name into identifier, replacing unsupported characters with the underscore (_) character.

Required for model referencing.

Tips

The code generator applies the identifier format specified by this parameter before it applies the formats specified by other identifier format control parameters.
Where possible, increase the Maximum identifier length to accommodate the length of the identifiers you expect to generate. Reserve at least three characters for name-mangling text.
If you specify $R, the value you specify for Maximum identifier length must be large enough to accommodate full expansions of the $R and $M tokens.
