how to generate 5 random matrix and in each of them i want to replace rows and columns ?

how to generate a 5 random matrix and in each of them i want to do this if i have (n,m) like A

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

i want a function to find

• the row that have ones > m/2 and between the group of ones just one zero
• the column that have ones > n/2 and between the group of ones just one zero

in this example the first row and third column

after that i want to generate a 5 random matrix and each of them must the first row and third column is equal to A like that

s = [ 1 0 1 1  
      1 1 0 0
      1 0 1 0
      1 1 1 0 ]

s = [ 1 0 1 1  
      1 1 0 1
      1 1 1 0
      1 0 1 1 ]

• Note the Matrix A will be large may be (50 x 50 )
