Multichannel Signals

Use standard MATLAB array syntax to work with multichannel signals. For example, a

multichannel signal consisting of the last three signals generated above is

z = [ramp_sig quad_sig sq_wave];

You can generate a multichannel unit sample function using the outer product operator.

For example, a six-element column vector whose first element is one, and whose

remaining five elements are zeros, is

a = [1 zeros(1,5)]';

To duplicate column vector a into a matrix without performing any multiplication, use

the MATLAB colon operator and the ones function:

c = a(:,ones(1,3));

1 2 ... 9 10 11 12 13 14 15 16 17 18 19 ... 59 60
