MATLAB: Delete the rows will all zeros in multi-dimensional matrix

MATLABmulti-channel matrixremove zeros

Dear all,
Let say I have a matrix M of size 6 x 3 x 3. And on each channel there are some zero rows (note that zero rows are evenly present in all channels). How can I remove the rows with all zeros.
For example,
M(:,:,1) =
     422   397   553
       0     0     0
       0     0     0
     476   494   520
       0     0     0
       0     0     0
M(:,:,2) =
       0     0     0
     384   494   504
       0     0     0
       0     0     0
     385   446   474
       0     0     0
M(:,:,3) =
             0           0           0
             0           0           0
          1194        1176        1295
             0           0           0
             0           0           0
          1202        1141        1295

Best Answer

out = reshape(M(bsxfun(@times,any(M,2),ones(1,size(M,2)))>0),[],size(M,2),size(M,3));
or only for your example
reshape(M(M>0),[],size(M,2),size(M,3))
