Natgrid(3NCARG)

💖 Natgrid (3NCARG) 💖

okay bestie, sit down, because this one is a whole package and I am obsessed. this is the Natgrid man page from NCAR GRAPHICS, and it's basically a package for gridding 2D randomly-spaced data using a natural neighbor algorithm. say it with me: natural neighbor algorithm. iconic. ✨

and guess what — there's single precision and double precision interfaces, in both Fortran and C. so many flavors, all of them yours. 💅

✨ NAME ✨

Natgrid — a package for gridding 2D randomly-spaced data using a natural neighbor algorithm. Single precision and double precision interfaces exist in both Fortran and C. 🦋

🌸 SYNOPSIS 🌸

💜 FORTRAN single precision

• NATGRIDS — primary function for gridding.
• NNSETI — set INTEGER parameter values.
• NNGETI — retrieve values for INTEGER parameters.
• NNSETR — set REAL parameter values.
• NNGETR — retrieve values for REAL parameters.
• NNSETC — set CHARACTER valued parameters.
• NNGETC — retrieve values for CHARACTER parameters.
• NNGETSLOPES — get slope values, if calculated.
• NNGETASPECTS — get aspect values, if calculated.
• NNPNTINITS — initiate single point mode.
• NNPNTS — interpolate at a single point.
• NNPNTEND — terminate single point mode.

💜 Fortran double precision (not supported on UNICOS)

bestie, heads up: UNICOS is not invited to this party. 🚫

🎀 ACCESS 🎀

to use Natgrid entries, load the NCAR Graphics library ngmath. that's it, that's the whole vibe check. 🫶

• Individual entries
• natgrid_params
• natgrid_errors

Complete documentation for Natgrid is available at this URL, bestie, go read it:

Also, an NCL (NCAR Command Language) interface exists for Natgrid procedures. two ways to eat, same snack. 🍓

and that's the whole page, no crumbs left 💅 this was the Natgrid page out of the NCAR GRAPHICS manual, last touched in March 1997-1998, and yeah it lives in the UNIX section. mwah. go grid something. 💖✨
