MATLAB: How to remove rows in a multidimensional matrix

for loopmultidimensional matrixremove rowsthree-dimensional

I have a three dimensional matrix (A) and I want to remove rows that contain 0. I tried to do this in a 'for loop', but it gives an error "A null assignment can have only one non-colon index.". When I replace [] with NaN, it seems the code and index are right. Does it possible to do this outside of 'for loop'? Thank you in advance for your help.
 clear all

A1 =  [50, 1, 130; 50, 1, 140; 0, 0, 0; 0, 0, 0];
A2 =  [0, 0, 0; 51, 2, 131; 51, 2, 141; 0, 0, 0];
A3 =  [0, 0, 0; 0, 0, 0; 52, 3, 132; 52, 3, 142];
A (:,:,1)= A1;
A (:,:,2) = A2;
A (:,:,3) = A3;
disp (A)
[r,c] = size(A);
for i = 1:3
    for h = 1:r
        if A (h,:,i) == 0
           A (h,:,i) = [] ;  % = NaN          
        end
    end
end
disp(A)

 for k=1:size(A,3)
   Ak = A(:,:,k);
   B(:,:,k)= Ak(sum(Ak')~=0,:);
 end
