For example, consider this vector A
A = [1 1 1 0 0 0 0 0].
I need all combinations of this vector so that there are 3 ones and 5 zeros. the number of combinations is 56 here.
I tried using randperm but I'm getting repeated vectors.
Kindly help solve this

J=nchoosek(1:8,3);
[m,n]=size(J);
I=repmat((1:m)',1,n);
accumarray([I(:) J(:)],1)
