In case if A and B are vectors ,( 1 x n ) matrices
A(B) % It will give the values of A at indexes B

idx = setdiff(1:length(A),B); % indexes which are not in B
A(idx) = 0;

Probably you want:
idx = setdiff(1:numel(A),B);
A(idx) = 0;

Beware this method works even if A is a matrix more than 1 dimension unlike the other.
