This problem could probably be explained a little better.

This is pretty simple given that there is a built in function to build magic squares. If not, the algorithm to "manually" build a magic square by filling a matrix is already well-known.

m= magic_sum(n)
z=magic(n);
m=sum(z(:));

why this aint working

@Anshul, Because here we want the sum of particular row, and your soln defines the sum of all the elements in the matrix!

x = magic(n);
y = sum(x);
m= randsample(y,1);
end
why it is wrong?
