Re: questions about ncarg library for interpolation routines

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:
