Wow, you sure do know how to complicate things. If you want to have M_row be "the number of ones in each row, and M_column be the number of ones in each column", you can simply do
M_row = sum(M, 2);
M_column = sum(M);
Instead of what you have:
M_row=cell2mat(cellfun(@(x) [x zeros(1,maxb-numel(x))],b_M,'un',0));
M_column=cell2mat(cellfun(@(x)[zeros(maxc-numel(x),1);x],c,'un',0));
Anyway, do you have an error that you want to ask about, but forgot to share with us?
