I have 3D matrix A=50x60x180 and I want subtract B=50x60 to get same size C=50x50x180? Can anybody use for loop to do this operation?

C = zeros(50,60,180);
for i = 1:180
C(:,:,i) = A(:,:,i) - B;
end
Is this what you mean?

?
size of the C -> [50x 50 x180]? Maybe - [50x 60 x180]

C = A - B;
or
C = bsxfun(@minus,A,B);

The first of those works in R2016b or later but not in earlier versions.
