I have an array of reals, like this.
0.1 0.1 0.1 0.1
0.2 0.2 0.2 0.2
0.1 0.2 0.3 0.4
How can I add the horizontal index value, so that the array ends up like this?
1.1 2.1 3.1 4.1
1.2 2.2 3.2 4.2
1.1 2.2 3.3 4.4
I could easily do it with a loop, but I'm convinced there is a one-line solution. I just can't see it.
PS the array is a lot larger than the example.
