if i Generate a binary random (n,m) matrix and after some steps i found A_matrix like this

 A_matrix = [ 1     1     1     1     1     1     1     1     1     1
              0     0     0     0     0     0     0     1     0     0
              1     1     1     1     1     1     1     0     1     1
              0     0     0     0     0     0     0     1     0     0
              1     0     0     0     0     0     0     1     0     0
              1     0     0     0     0     0     0     1     0     0 ]

i want to generate another randomly matrix but i want

the row that have more than the half of ones compered by m (number of ones > m/2) copy as it is in the new matrix
the column that have more than the half of ones comperd by n (number of ones > n/2) copy as it is in the new matrix

 X_before = [ 1    0    0    1    0    0    1    0    1    0
              1    0    1    0    0    0    1    0    1    0
              0    1    0    1    0    1    0    0    0    0
              0    0    1    0    1    0    0    1    0    1
              0    1    0    1    0    1    0    0    1    1
              0    0    1    0    1    1    1    0    0    0 ]
 X_after = [ 1     1     1     1     1     1     1     1     1     1
             0     0     1     0     0     0     1     1     0     0
             1     1     1     1     1     1     1     0     1     1
             0     1     0     1     0     1     0     1     0     0
             1     0     1     0     1     0     0     1     0     1
             1     1     0     1     0     1     0     1     1     1 ]
 where A_matrix (1,:) and (3,:) and (:,8) are equal to X_after (1,:) and (3,:) and (:,8)
