if i have (n,m) Binary matrix A like this
A = [ 0 0 0 0 1
1 0 1 1 1
0 0 0 0 0
0 0 0 0 1 ]
and i want to generate a binary random matrix and make a a rows and columns that have ones in A
to be in the same position in the random matrix like that
before the function S_rand = [ 1 0 1 0 0
1 1 0 1 0
0 1 0 1 1
0 0 1 0 1 ]
after the function S = [ 1 0 1 0 1
1 0 1 1 1
0 1 0 1 0
0 0 1 0 1 ]
where in S the second row and last column is the same in A

S_rand(selected_row, :) = A(selected_row, :);
S_rand(:, selected_col) = A(:, selected_col);
