How can I change column values from a matrix?

Hi, I have to add [column number - 1]*0.5 to each column from a matrix,

For example:

0 0 0 0 0

1 1 1 1 1

2 2 2 2 2

3 3 3 3 3

to

0 0.5 1.0 1.5 2.0

1 1.5 2.0 2.5 3.0

2 2.5 3.0 3.5 4.0

3 3.5 4.0 4.5 5.0

I have to do that for an imported 700x20 matrix that already exists, maybe using for function, but I don't know how.
