There is a relatively simple task that I wonder how we can use gmt math to do for:

If we want to have a “time series”, we can simply do

`gmt math -o0 -T1.e-4/1.e-2/2+l T =`

to get the column of the data values (-o0 was used to suppress the duplicated column):

0.0001

0.0002

0.0005

0.001

0.002

0.005

0.01

Problem is, sometime I want to append “smartly” the indexing integers for each row; the final result I want in this case would be:

1 0.0001

2 0.0002

3 0.0005

4 0.001

5 0.002

6 0.005

7 0.01

The 1…7 list can also easily be generated using another gmt math command:

gmt math -o0 -T1/7/1 T =

But is there a way to generate the two columns AT ONCE using gmt math ?

Thanks
