Exporting Signals
3-77
The workspace matrix always has time running along its first (P) dimension.
Samples are saved along the P dimension whether the input is a matrix, vector,
or scalar (single channel).
The following example illustrates how the To Workspace block can be used to
export a frame-based multichannel signal to the MATLAB workspace.
Example: Exporting a Frame-Based Signal. In the model below, the To Workspace
block exports a three-channel frame-based signal with the following data:
•
Channel 1: 1, 2, 3, 4, 5,..., 100, 0, 0, 0,...
•
Channel 2: -1, -2, -3, -4, -5,..., -100, 0, 0, 0,...
•
Channel 3: 5, 5, 5, 5, 5,..., 0, 0, 0,...
