For Iterator Subsystem

Repeat subsystem execution during simulation time step for specified number of iterations

Description

The For Iterator Subsystem block is a Subsystem block preconfigured as a starting point for creating a subsystem that repeats the execution during a simulation time step for a specified number of iterations. The number of iterations is controlled by a For Iterator block inside the subsystem. For an example, see ex_for_iterator_block.

When using simplified initialization mode, if you place a block that needs elapsed time (such as a Discrete-Time Integrator block) in a For Iterator Subsystem block, Simulink^® displays an error.

Examples

Iterated Assignment with the Assignment Block

Using the Assignment block to assign values computed in a For or While Iterator loop to successive elements.

Open Model

Ports

Input

In — Signal input to a subsystem block

scalar | vector | matrix

Placing an Inport block in a subsystem adds an external input port to the Subsystem block. The port label matches the name of the Inport block.

Use Inport blocks to get signals from the local environment.

Data Types: half | single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus | image

Output

Out — Signal output from a subsystem

scalar | vector | matrix

Placing an Outport block in a subsystem adds an output port from the Subsystem block. The port label on the Subsystem block is the name of the Outport block.

Use Outport blocks to send signals to the local environment.

Data Types: half | single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | Boolean | fixed point | enumerated | bus | image
