Writing S-Functions

ssSetInputPortSampleTime

Specify the sample time of an input port

Syntax

• ssSetInputPortSampleTime(SimStruct *S,inputPortIdx,period)
  

Arguments

S
   SimStruct representing an S-Function block or a Simulink model.

inputPortIdx
   Index of the input port whose sample time is being set.

• period
  

Sample period.

Description

Use in mdlInitializeSizes (after ssSetNumInputPorts) to specify the sample time period as continuous or as a discrete value for each input port. Input port index numbers start at 0 and end at the total number of input ports minus 1. You should use this macro only if you have specified port-based sample times.
