I have a matrix A(52,4) with some values in it and I have another matrix B(52,1) with 1's and 0's in it. I want to control the B matrix and if the B matrix's value is 1 in the following index then I want to make the A matrix's that index full of zeros.With for loop I can do it as it follows but is it possible in matlab to make it in another way and get rid of this for loop?
for a=1:52
if B(a,1)==1
A(a,:)=0
end
end
thank you

A(B(:, 1)==1,:) = 0;
Or
A(logical(B), :) = 0;
If you were to maintain B as logical instead of numeric then just
A(B, :) = 0;
