Writing S-Functions

ssSetSFcnParamNotTunable

Make a block parameter nontunable

Syntax

• void ssSetSFcnParamNotTunable(SimStruct *S, int_T index)
  

Arguments

S
   SimStruct representing an S-Function block.

index
   Index of the parameter to be made nontunable.

Description

Use this macro in mdlInitializeSizes to specify that a parameter doesn't change during the simulation, where index starts at 0 and is less than ssGetSFcnParamsCount(S). This improves efficiency and provides error handling in the event that an attempt is made to change the parameter.

Note    This macro is obsolete. It is provided only for compatibility with S-functions created with earlier versions of Simulink.
