Hi,

I am assigning a 3D array, which contains some information for a number of different loadcases. Each row in the array defines a particular loadcase (of which there are 3) and I would like to remove the loadcase (i.e. the row) if ALL the elements of the row (in 3D) are equal to zero.

The code I have at the moment is: Array = zeros(3,5) % Initialise array

               Numloadcases = 3;
      Array(:,:,1) = [10 10 10 10 10;
                      0   0  0  0  0;
                      0   0  0  0  0;]; % Expand to a 3D array 

      Array(:,:,2) = [10 10 10 10 10;
                      0  0  0  0  0;
                      0  0  0  0  0;];

     Array(:,:,3) = [10 10 10 10 10;
                      0  0  0  0  0;
                      0  0  20  0  0;];

      Array(:,:,4) = [10 10 10 10 10;
                      0  0  0  0  0;
                      0  0  20  0  0;];

% I.e. the second row should be removed.

                  for i = 1:Numloadcases
                      if sum(Array(i,:,:)) == 0;
                      Array(i,:,:) = []

                      end
                  end

At the moment, the for loop I have to remove the rows causes an indexing error, as the size of the array changes in the loop.

Can anyone see a work around for this?

Thanks
