Fold temporary variable using function block instance output variable

Optimize output variables by using expression folding

Since R2022b

Model Configuration Pane: PLC Code Generation / Optimization

Description

The Fold temporary variable using Function Block instance output variable parameter optimizes the code for the output variables of function blocks generated from reusable Simulink^® subsystems, Stateflow^® charts, or MATLAB^® Function blocks by removing temporary variable assignments that are not required.

Settings

Default: off

On: Generates optimized code for output variables of function blocks by folding temporary variables into a single expression.
Off: The generated code for function block instance output variables uses temporary variable assignments.
