Hi, I have three variables, BoxA and BoxB. Where BoxA=1, BoxB=2. I would like it so that if I can pick randomly between BoxB and BoxC. Thank you.

What is BoxC ??

Anyhow, to pick N by M random values from a list:

rvals = [BoxA, BoxB];   %expand the list if you have reason
randompicks = rvals(ceil(rand(N, M) * length(rvals)));

I believe there is also a Stats toolbox function to do random sampling of exactly this kind.
