For example : A=[ 0 3 2 5 0 3 1 1 2 2; 5 8 6 6 1 0 0 2 3 3; 7 9 9 7 0 0 0 0 0 0; 8 10 10 9 9 8 10 6 5 7;] And column order that have maximum values zero : 5 6 7 1 8 9 10 2 3 4

A=[ 0 3 2 5 0 3 1 1 2 2; 5 8 6 6 1 0 0 2 3 3; 7 9 9 7 0 0 0 0 0 0; 8 10 10 9 9 8 10 6 5 7;] ;
[m,n] = size(A) ;
c = zeros(m,1) ;
for i = 1:m
c(i) = n-nnz(A(i,:)) ;
end
[val,idx] = sort(c) ;
A = A(idx,:) ;

[~, idx] = sort(sum(A == 0), 'descend')
