Supported Variable Types in Embedded MATLAB Functions

Embedded MATLAB functions support a subset of MATLAB data types for input (argument) and output (return) variables, and variables local to the function. This section lists and describes the data types supported in Embedded MATLAB functions, along with any exceptions or deviations from MATLAB behavior.

Embedded MATLAB functions support scalar, vector, and matrix (two-dimensional) variables of the types represented by the following cast functions:

Type/Function
Description

char
Character array (string)

complex
Complex data. Cast function takes real and imaginary components. See Using Complex Data in Embedded MATLAB Functions in Simulink online documentation.

double
Double-precision floating point

int8, int16, int32
Signed integer

logical
Boolean true or false

single
Single-precision floating point

uint8, uint16, uint32
Unsigned integer

Type/Function	Description
`char`	Character array (string)
`complex`	Complex data. Cast function takes real and imaginary components. See Using Complex Data in Embedded MATLAB Functions in Simulink online documentation.
`double`	Double-precision floating point
`int8,` `int16,` `int32`	Signed integer
`logical`	Boolean t`rue` or `false`
`single`	Single-precision floating point
`uint8,` `uint16,` `uint32`	Unsigned integer
