Interpolation of Irregularly and Regularly Spaced Data
Description
Several cubic spline interpolation methods of H. Akima for irregular and
regular gridded data are available through this package, both for the bivariate case
(irregular data: ACM 526 and ACM 761, regular data: ACM 433) and univariate case (ACM 697).
Linear interpolation of irregular gridded data is also covered by reusing D. J. Renkas
triangulation code which is part of Akimas Fortran code.
