[ncl-talk] question about sorting

[Damjan Jelić]

Dear NCL support,

i have perhaps a bit silly question but i stuck up and have to ask:

suppose i have 2D array like:
   2015     1     1
   2016     2     1
   1981     1     2
   1982     1     0
   1981     0     2
how can i sort it out in a way that first column is from 1981-2016 but 
rows stay attached to the year so on the end it looks like this:

   1981     1     2
   1981     0     2
   1982     1     0
   2015     1     1
   2016     2     1

the order within same year (1981) is not relevant.
Is there some NCL function for that and how to use it correctly?

Kindly,
Damjan
