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.
