Importing Signals
3-65
•Form output after final data value = Setting to zero
The Signal expression [A B] uses the standard MATLAB syntax for
horizontally concatenating matrices and appends column vector
B to the right
of matrix
A. Equivalently, you could set Signal = C, and define C at the
command line by
C = [A B]
The Sample time setting of 1 yields a sample-based output with sample period
of 1 second. The
Form output after final data value parameter setting
specifies that all outputs after the third are zero.
Importing a Sample-Based Matrix Signal
The Signal From Workspace block generates a sample-based matrix signal
when the variable (or expression) in the
Signal parameter is a
three-dimensional array and
Samples per frame = 1. Beginning with the first
page of the array, the block releases a single page (i.e., matrix) of the array to
the output at each sample time. Therefore, if the
Signal parameter specifies an
M-by-N-by-P array, the output of the Signal From Workspace block is an
M-by-N matrix, representing M
∗N channels.
The figure below illustrates this for a 6-by-4-by-5 workspace array
A.
