Hi,,I am trying to calculate the weight of a matrix.how can i do that> I am explaining below

Suppose I have a matrix...

A = [1 0 0 0 ;
     1 1 0 0 ;
     1 1 1 0 ;
     1 1 1 1]

how do I calculate that how many coulmns have only one ONE ? TIA

Is it possible to do the same with the rows?? TIA

numberOfRowsThatHaveExactlyOneOne = sum(sum(A==1,2)==1,1);
