Constructing Sample-Based Multichannel Signals
from Existing Sample-Based Multichannel Signals

You can combine existing multichannel sample-based signals into a larger multichannel signal by using the Matrix Concatenation block in the Simulink Sources library.

Example: Concatenating Multichannel Signals.   The model below shows two two-channel sample-based signals (four channels total) being combined into a 2-by-2 multichannel matrix signal.

To build the model, make the following parameter settings:

• In Signal From Workspace, set Signal = [1:10;-1:-1:-10]'
• In Signal From Workspace1, set Signal = [zeros(10,1) 5*ones(10,1)]
• In Matrix Concatenation, set:
• Number of inputs = 2
• Concatenation method = Vertical

Each 2-by-2 output from the Matrix Concatenation block contains both samples from each of the two input signals, so that all four samples in the output correspond to the same instant in time. See Sample-Based Multichannel Signals for more about sample-based signals.
