[ncl-talk] sort multiple 1D vectors with a common timestamp according to one, without a loop

[Matthew Fearon]

Thanks, Rick. I just tried a small example as you suggested. I think dim_pqsort is sorting as we thought. However, though carries along an assigned coordinate variable, it doesn't appear to sort it with the data as qsort would. I think I can piece something together. Thanks for the help.

Hi Matt,

I don't know definitively, but my reading of the docs on dim_pqsort suggest, along with its attendant example #2, suggest that it does indeed do what you want.  You could cobble together a small test case to verify.

HTH...

Does dim_pqsort do this?

In my example, if I did  x = dim_pqsort(precip, -2) , is x the indices of the sorted array (descending) that I could apply to the other variables to order them consistent with precip?

thanks for the help.

Dear NCL users,

Trying to sort multiple 1D vectors according to one primary vector. For example, I have temp, rh, wind, and precip as 1D vectors of the same length, and they corresponding in time. How can I sort precip descending and attached the corresponding temp, rh, and wind to it, without a loop?

thanks,
Matt
