2D subtraction from 3D

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?

[John Chilleri]

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]

Answer 1

[Andrei Bobrov]

C = A - B;

or

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

[Walter Roberson]

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

Walter! I am agree with you!
