How to remove zeros from a 3D array

Hi everyone, I have a 3D array like this A(v,n,m) , I need to remove zero columns and and rows from first 2 dimens

     for m=1:N
    A(~any(A,2),:,m)=[];
    A(:,~any(A,1),:m)=[];
    end

I tried this code but I got error. If anyone can help me, appreciated.

If you remove the zeros.....the dimensions of the matrix changes...Is that okay?

Burak - are you trying to remove all columns or rows that are all zeros or at least one zero in that row or column? If there is a row to be removed at A(1,:,1) do you remove this row from A(1,:,k) for all k?

@KSSV yes, dimensions change and it is ok, I need to get inverse of A for all m but there are zeros and it can't be inversed.

@Geoff I need to remove all rows for A(1,:,k), A(2,:,k) ,...,A(n,:,N) etc.

By the way, thank you both for your interest.

Well, you cannot remove a row of column from one page but not the other pages, so the loop does not make much sense.

You could do this:

A(any(~any(A, 2), 3)) = [];  %remove row from all pages when one row in any of the pages has a 0
A(any(~any(A, 1), 3)) = [];  %remove column from all pages when one column in any of the pages has a 0

if that is appropriate for you.

I will try this, thank you for your interest.

it didn't work , because A's size change when we remove zeros.
