SetAllowConstantSampleTime

Specify sample time behavior and tunability for S-function blocks with port-based sample times

Language

MATLAB^®

Syntax

SetAllowConstantSampleTime(s,flag)

Arguments

s

Instance of Simulink.MSFcnRunTimeBlock class representing the Level-2 MATLAB S-Function block.

flag

Logical value to allow a sample time of Inf for ports in the S-function. The default is False.

Description

Use this macro to specify sample time behavior for your S-function with port-based sample times. If you set flag to False, the Simulink engine does not allow a sample time of Inf for this S-function. If you set flag to True, the S-function block is tunable and its ports can have a sample time of Inf. To set the sample time for ports in the S-function, use SetInputPortSampleTime and SetOutputPortSampleTime. These ports execute every time you tune any parameter in your model during simulation.
