MATLAB: How to generate a single random number

functionrandomrandom number generator

I need to generate a single random number within my code. Is there a function to do this?

rand  % random number between 0 and 1

%or

randi(100)  % integer random number between 1 and 100

out=stream(randi(length(stream)));

combvec() from the Deep learning toolbox is most easiest solution

a = [1 2 3]
b = [1 2 3]
C = combvec(a, b).'; % if the order of column is important: C = fliplr(combvec(a, b).');

The other solution is to use ndgrid()

a = [1 2 3]
b = [1 2 3]
[A, B] = ndgrid(a, b);
C = [B(:) A(:)]
