How can I subtract a 2-d array from every slice of a 3-d array?

A is a 512 x 512 x 200 array representing a stack of 200 monochrome images of resolution 512x512.

d = size(A)

d =
     512     512     200

C is an 'offset' image that I want to deduct from each image in A. C has dimensions 512 x 512.

A(:,:,1) = A(:,:,1) - C;
A(:,:,2) = A(:,:,2) - C;
A(:,:,3) = A(:,:,3) - C;
A(:,:,4) = A(:,:,4) - C;
% and so on

I know that I could do a 'for' loop to handle this. Is there a better 'one-line' solution?

A = randi(9, 5, 5, 3);
C  = randi(9, 5, 5);

newA = A - C;

%demonstrate that it worked
A(:,:,1)

ans = 5×5

3 2 2 9 1 6 8 6 1 5 5 1 5 6 2 6 6 2 5 7 7 4 8 5 7

C

C = 5×5

5 6 5 8 1 2 7 9 3 7 9 7 5 7 2 1 6 8 9 6 8 4 2 5 8

A(:,:,1) - C

ans = 5×5

-2 -4 -3 1 0 4 1 -3 -2 -2 -4 -6 0 -1 0 5 0 -6 -4 1 -1 0 6 0 -1

newA(:,:,1)

ans = 5×5

-2 -4 -3 1 0 4 1 -3 -2 -2 -4 -6 0 -1 0 5 0 -6 -4 1 -1 0 6 0 -1

Perfect. Thank you, Walter.
