Multiply each number in a matrix by the diagonal number of a given row using a for loop

I have this matrix here
a=[2 -5 7;1 1 3;4 5 12];
I need to multiply each of the numbers in the row by the diagonal of that row using a for loop. So afterwards it should look like this
a=[4 -10 14;1 1 3;48 60 144]
I have no idea on how to do this, so any help on how to do this is appreciated, thank you.

b=bsxfun(@times,a,diag(a))
