Using Simulink

Data Types Supported by Simulink

Simulink supports all built-in MATLAB data types. The term built-in data type refers to data types defined by MATLAB itself as opposed to data types defined by MATLAB users. Unless otherwise specified, the term data type in the Simulink documentation refers to built-in data types. The following table lists MATLAB's built-in data types.

Name	Description
double	Double-precision floating point
single	Single-precision floating point
int8	Signed eight-bit integer
uint8	Unsigned eight-bit integer
int16	Signed 16-bit integer
uint16	Unsigned 16-bit integer
int32	Signed 32-bit integer
uint32	Unsigned 32-bit integer

Besides the built-in types, Simulink defines a boolean (1 or 0) type, instances of which are represented internally by uint8 values.
