String Count

Count occurrences of pattern in string

Since R2020a

• 

Libraries:
Simulink / String

Description

The String Count block counts the occurrences of the pattern (sub) in a string (str). If the input at sub matches part or all of the input at str, the block counts the occurrence as 1.

Ports

Input

str — String to search

scalar

String to search for the pattern in, specified as a scalar.

Data Types: string

sub — String pattern to search for

scalar

String pattern to search for in string, specified as a scalar.

Data Types: string

Output

n — Number of times pattern was found in string

scalar

Number of times the string pattern was found in the string, str, returned as a scalar.

Data Types: int8 | uint8 | int16 | uint16 | int32 | uint32

Parameters

Case sensitive — Case sensitivity

on (default) | off

Case sensitivity for the string count:

on

Consider string case when counting found strings.

off

Do not consider string case when counting found strings.

Programmatic Use

Block Parameter: CaseSensitive

Type: character vector

Values: 'on' | 'off'

Default: 'on'

Output data type — Output data type

Inherit: Inherit via internal rule (default) | Inherit: Inherit via back propagation | int8 | uint8 | int16 | uint16 | int32 | uint32 | <data type expression>

Output data type. The type can be inherited, specified directly, or expressed as a data type object such as Simulink.NumericType.

When you select an inherited option, the block exhibits these behaviors:

• Inherit: Inherit via internal rule — Simulink^® chooses a data type to balance numerical accuracy, performance, and generated code size, while taking into account the properties of the embedded target hardware.

• Inherit: Inherit via back propagation — Use data type of the driving block.

Click the Show data type assistant button to display the Data Type Assistant, which helps you set the data type attributes. See Specify Data Types Using Data Type Assistant for more information.

Programmatic Use

Block Parameter: OutDataTypeStr

Type: character vector

Values: 'Inherit: Inherit via internal rule' | 'Inherit: Inherit via back propagation' | 'int8' | 'uint8' | 'int16' | 'uint16' | 'int32' | 'uint32' | <data type expression>

Default: 'Inherit: Inherit via internal rule'

Mode — Category of data type

Inherit (default) | Built in | Expression

Category of data type, specified as Inherit, Built in, or Expression. For more information on using this parameter, see Specify Data Types Using Data Type Assistant.
