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.
