Re: questions about ncarg library for interpolation routines

Jemma,

Dave found some commented out code in our HLU library that contains some of these routines, but we're not sure of the nature of them.

If you download the NCL source code, and look in $NCARG/ni/src/lib/hlu, you'll see the files like:

coeff1.f
interp.f
terp1.f

Looking through these, some of subroutines are commented out, so they don't show up in our "hlu" library. However you might be able to uncomment them and compile them, if you build NCL from source code.

I'll attach them here.

I found the codes call some ncarg interpolation subroutines (coeff2, terp2, interp, etc) which were in the cubspl package (?) of version 4. But I couldn't find this package in the ncarg.v5 lib that I installed. Could you point to me which package they are in? and are these subroutines still the same with version 4?
