I ma having matrix A=[
44 0 0;
0 57 0;
0 1 48]
The sum(A) is 150.
Could anyone please help me how to make the matrix such that sum of each row of the matrix be 50 under the condition the diagonal of the matrix should contain the maximum number greater than 45 and the rest of the place can have the number ranging from 1 to 5.

Well you cannot for that matrix. The second row contains 57 so the minimum sum for the row cannot be less than 57 but you need it to be 50.

P = rand(3,1)*3+45;
Q = (50 - P - 1).*rand(3,1) + 1;
R = 50 - P - Q;
A = [P, Q, R] ;
Now circshift row 2 by 1 right and circshift row 3 by 2 right.
