Perform element-wise subtraction
Library
Math Functions / Math Operations
Description
The Subtract block performs element-wise subtraction of two input signals.
The block warns or errors out when an integer output overflows during simulation. To configure, select for your model in the Simulink Editor, then set the Wrap on overflow or Saturate on overflow parameter.
Data Type Support
The Subtract block supports any floating point, fixed-point, integer or Boolean data type. The block can perform element-wise subtraction on real and complex inputs. The input signals can be scalars, vectors or matrices. When both inputs have non-scalar dimensions, the dimensions must match each other.
Parameters
Saturate on integer overflow
This parameter specifies whether integer overflow is handled by wrapping (default) or by saturating. This parameter is relevant only if the output is integral (int8, int16, int32, uint8, uint16, uint32).
Settings for the Saturate on integer overflow parameter are:
| Setting | Description |
|---|---|
| Not selected | Integer overflow is handled by wrapping. |
| Selected | Integer overflow is handled by saturation. |
When overflow is detected, the Diagnostic Viewer displays messages that depend on the diagnostic action you specify in the Simulink Editor. To configure, select for your model in the Simulink Editor, then set the Wrap on overflow or Saturate on overflow parameter.
