How can I add an index value to an array value?

1 view (last 30 days)
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.

M = [0.1,0.1,0.1,0.1;0.2,0.2,0.2,0.2;0.1,0.2,0.3,0.4]
M = 3×4
0.1000 0.1000 0.1000 0.1000 0.2000 0.2000 0.2000 0.2000 0.1000 0.2000 0.3000 0.4000
M = M + (1:size(M,2))
M = 3×4
1.1000 2.1000 3.1000 4.1000 1.2000 2.2000 3.2000 4.2000 1.1000 2.2000 3.3000 4.4000
