ssSetNumIWork

Specify the size of a block's integer work vector.

Syntax

• void ssSetNumIWork(SimStruct *S, int_T nIWork)
  

Arguments

S
   SimStruct representing an S-Function block.

nIWork
   Number of elements in the integer work vector.

Description

Use in mdlInitializeSizes to specify the number of int_T work vector elements as 0, a positive integer, or DYNAMICALLY_SIZED. If you specify DYNAMICALLY_SIZED, you can specify the true (positive integer) width in mdlSetWorkWidths; otherwise, the width used is the width of the signal passing through the block.
