This seems to just be a vector of 1's length of the number of observations (scans). Is there anything wrong with just making this without using the below code?

dof(ii) = sum(mat(ii,1) > 0); %#ok

I should add that I looked at the matrix mat and across the diagonal is changing but down the diagonal is the same value. I can show you monday.
