Writing S-Functions

ssSetIWorkValue

Set an element of a block's integer work vector.

Syntax

• int_T ssSetIWorkValue(SimStruct *S, int_T idx, int_T value)
  

Arguments

S
   SimStruct representing an S-Function block.

idx
   Index of the element to be set

value
   New value of element

Description

Sets the idx element of S's integer work vector to value. The vector consists of elements of type int_T and is of length ssGetNumIWork(S). Typically, this vector is initialized in mdlStart or mdlInitializeConditions, updated in mdlUpdate, and used in mdlOutputs. You can use this macro in the simulation loop, mdlInitializeConditions, or mdlStart routines. This macro returns the value that it sets.

Example

The following statement

• ssSetIWorkValue(s, 0, 1);
  

sets the first element of the work vector to 1.
