Thread Subject: random source generator?

Hello,
I need to generate n random symbols from the foloowing
I have 4 symbols a) (1,0) b) (-1,0) c) (0,3) d) (0,-3).

Which command do i need to use for this.

I used randsrc(), but how should the alphabet parameter be passed [1,0,-1,3,-3] will generate all possible combinations...But i need only the above a,b c and d symbols.


Thanks!.

if the symbols can be complex:

randsrc(m,1,[1,-1,3i,-3i]);

or if they must be real vectors:

c=[1 0; -1 0; 0 3; 0 -3];
c(1+floor(4*rand(m,1)),:);
