ssSetOutputPortSampleTime - Specify the sample time of an output port

Syntax

real_T ssSetOutputPortSampleTime(SimStruct *S, int_T outputPortIdx,
 time_T period)

Arguments

S: SimStruct representing an S-Function block.
outputPortIdx: Index of the output port whose sample time is being set.
period: Sample time of the output port.

Returns

The real_T value of the sample time passed into the macro.

Description

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

If the S-function specifies INHERITED_SAMPLE_TIME for any of its ports, the S-function should include an mdlSetOutputPortSampleTime callback method. The callback method should set the sample time and offset of ports that inherit their sample time to the status that the Simulink engine assigns to them using its sample time propagation rules. The callback method can also assign the sample times and offsets of other ports on the block whose sample times are inherited.
