Using Variable-Size Signals on the Delay Block
This example shows how the Delay block supports variable-size signals for sample-based processing. The Switch block controls whether the input signal to the enabled subsystem is a 3-by-3 or 3-by-2 matrix.
The Delay block appears inside the enabled subsystem.
The model follows these rules for variable-size signals while using sample-based processing.
Signal dimensions change only during state reset when the block is enabled.
Initial condition must be scalar.
The rules are implemented by these blocks.
