Signal Processing Toolbox

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 = [t t.^2 square(4*t)];

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 MATLAB's colon operator and the ones function.

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