Importing Signals
3-71
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 and Samples per frame setting of 4 yield a
frame-based output with sample period of 1 second and frame period of
4 seconds. The
Form output after final data value parameter setting
specifies that all samples after the hundredth are zero.
