Function-Call Generator - Execute function-call subsystem specified number of times at specified rate

Library

Ports & Subsystems

Description

The Function-Call Generator block executes a function-call subsystem (for example, a Stateflow^® chart acting as a function-call subsystem) at the rate you specify for the Sample time parameter. To execute multiple function-call subsystems in a prescribed order, first connect a Function-Call Generator block to a Demux block that has as many output ports as there are function-call subsystems to control. Then connect the output ports of the Demux block to the systems to control. The system connected to the first demux port executes first, the system connected to the second demux port executes second, and so on.

Data Type Support

The Function-Call Generator block outputs a signal of type fcn_call.

Parameters and Dialog Box

Sample time

The time interval between samples. See How to Specify the Sample Time in the online documentation for more information.

Number of iterations

Number of times to execute the block per time step. The value of this parameter can be a vector where each element of the vector specifies a number of times to execute a function-call subsystem. The total number of times that a function-call subsystem executes per time step equals the sum of the values of the elements of the generator signal entering its control port.

Suppose that you specify the number of iterations to be [2 2] and connect the output of this block to the control port of a function-call subsystem. In this case, the function-call subsystem executes four times at each time step.
