You do not want to store the results in separate variables R1, R2, etc., but rather as elements of a single variable R, with R(1), R(2), etc.

A = magic(3)

RowSum = sum(R,2)

What do you mean, "not working"? Did you read the help of sum?

May be you want to sum along rows rows, i.e., sum the elements in each column?

ColumnSum = sum(R,1)

Next time, be a little bit more specific ...
