Number of raws = M, number of columns = N, number of one's in each row = Nrow, number of one's in each column = Ncolumn.

This will not work in general: You cannot e.g. place 2 elements per row and per column in a 5 x 5 matrix:
1 0 0 0 0 % <-- here one 1 is missing and cannot be inserted
1 1 0 0 0
0 1 1 0 0
0 0 1 1 0
0 0 0 1 1
But you can create a 6x6 matrix with 3 ones in each column and row.

Your example does not appear to be complete.
[0 0 1 1 0; 0 1 1 0 0; 1 1 0 0 0; 1 0 0 0 1; 0 0 0 1 1]
ans =
0 0 1 1 0
0 1 1 0 0
1 1 0 0 0
1 0 0 0 1
0 0 0 1 1
This is a 5 x 5 matrix with two 1's per row and per column.
Furthermore for your original matrix, insert the 1 at the top right corner:
1 0 0 0 1
1 1 0 0 0
0 1 1 0 0
0 0 1 1 0
0 0 0 1 1
