ssIsSpecialSampleHit

Determine whether sample is hit

Syntax

• ssIsSpecialSampleHit(SimStruct *S, sti1, sti2, tid)
  

Arguments

S
   SimStruct representing an S-Function block.

sti1
   Index of the sample time.

sti2
   Index of the sample time.

tid
   Task ID.

Description

Returns true if a sample hit has occurred at sti1 and a sample hit has also occurred at sti2 in the same time step.
