>> V = [0.01,-0.01];
>> V(randi(numel(V),5,5))
ans =
-0.010000 0.010000 -0.010000 0.010000 0.010000
-0.010000 0.010000 0.010000 0.010000 -0.010000
-0.010000 -0.010000 0.010000 0.010000 -0.010000
0.010000 -0.010000 -0.010000 -0.010000 -0.010000
-0.010000 0.010000 -0.010000 0.010000 -0.010000
Although you could calculate the values from randi, this method using indexing has the advantage that the values are not calculated but are exactly those values that you define in V.
