Hello,
Can someone guide me how to generate a random matrix in Matlab with only specific values in it.
For example, lets say I need a 1*100 element array with values only 0,90,180 in it. How can I do it using Matlab.
Many Thanks

valueset = [0, 90, 180];
desiredsize = [1, 100];
desiredmatrix = valueset(randi(numel(valueset), desiredsize))
