[ncl-install] questions about ncarg library for interpolation routines

[Fred Clare]

Jemma,

Attached is complete source for the old cubic spline interpolation
package.  Dick Valent was able to dig this up.  The package has seven
routines: coeff1, terp1, coeff2, terp2, trip, search, interp.  All of
these are part of the HLU distribution, except for coeff2 and terp2.

If you want to stay current, in place of using the cubic spline package,
I would recommend using the more recent functions documented in
the Fitgrid package at:
