I generated this code and was wondering if there was any way to have it to the same function with using a while loop?

function B=Sudoku(A)
[m,n]=size(A);
if m~=n
    error('The matrix is not square')
end
R=sum(A,1);
C=sum(A,2);
D=abs(diff(R));
E=abs(diff(C));
if any(D)||any(E) > 10^-7
    error('the sums are not the same')
else if all(D)&& all(E) <10^-7
        disp(C(1,1))
    end
end
B=C(1,1);

Your conditional statements are likely not to be correct actually; for example

all(D) && all(E) < 10^-7

will be evaluate as the AND (short-circuit) between array D (where zero elements are interpreted as logical false and the others as true) and the outcome of the test with the relational operator (which is a logical array of element-wise < 10^-7, based on E).

What would you like to "loop" in this function?
