String Concatenate

R2026b

Concatenate input strings to form one output string

• 

String Concatenate block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
Simulink / String

Description

The String Concatenate block concatenates multiple input strings, in order of their input, to form one output string. Use this block if you want to combine multiple strings into a single string.

Ports

Input

Port_1 — First input string

scalar

First input string, specified as a scalar.

Data Types: string

Port_2 — Second input string

scalar

Second input string, specified as a scalar.

Data Types: string

Output

Port_1 — Concatenated string

scalar

Concatenated string, specified as a scalar.

Data Types: string

Parameters

Number of Inputs — Number of input strings

scalar

Number of input strings to concatenate, specified as a scalar. You can specify from 2 to 512 input ports.

Programmatic Use

Block Parameter: Inputs

Type: character vector

Values: scalar from 2 to 512

Default: '2'

Output data type — Output data type

string (default) | <data type expression> | scalar

Output data type, specified using the string data type to specify a string with no maximum length.

To specify a string data type with a maximum length, specify stringtype(N). For example, stringtype(128) creates a string data type with a maximum length of 128 characters.

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: 'string' | <data type expression>

Default: 'string'

Mode — Category of data

stringtype(128) (default) | scalar

Use the stringtype function, for example, stringtype(128).

Dependency

Clicking the Show data type assistant button enables this parameter.
