how can i separate those columns which have same number of rows (e.g. the highlighted ones with fixed 7 rows ) by excluding zeros?

how can i separate those columns from the data arrays which have same number of rows (e.g. the highlighted ones with fixed 7 rows ) by excluding zeros?

Let A be your matrix.

B = A(:,sum(A>0)==7)  ; % pick the required columns 
iwant = B(sum(B,2)>0,:) ; % remove the zeros if any in rows

I have assumed that all the numbers are positive in A.
