Preserve MATLAB® namespaces in generated code

Specify whether generated code for enumeration in MATLAB namespace includes the namespace in the type definition

Since R2025a

Model Configuration Pane: Code Generation / Interface

Description

The Preserve MATLAB namespaces in generated code parameter specifies whether the code generator includes the namespace in the generated type definition of an enumerated type that is derived from a Simulink.IntEnumType object and is defined inside a MATLAB namespace. For C++ code generation, the code generator generates the enumeration in a namespace. For C code generation, the code generator prefixes the enumeration with the MATLAB namespace.

This table displays the generated code for enumerated type Colors in the MATLAB namespace MyColors with the parameter set to On and Off.

typedef enum {
    black,

} MyColors_Colors;

typedef enum {
    black,
    white
}  Colors;
C++ 
namespace MyColors {
    enum class Colors : int32_t {
        black,
        white
    };
}

enum class Colors : int32_t {
        black,
        white
    };

Settings

On (default) | Off
On

The generated type definition includes the MATLAB namespace where the enumeration is defined.

Off

The generated type definition does not include the MATLAB namespace where the enumeration is defined.
