REGRIDPACK


REGRIDPACK is a suite of Fortran 77 routines for interpolating values between one-, two-, three-, and four-dimensional arrays defined on uniform or nonuniform orthogonal grids. This operation is commonly referred to as "regridding." Linear or cubic interpolation can be selected independently in each dimension. Extrapolation is not allowed. The subroutines in REGRIDPACK cannot be used to transfer values on nonorthogonal (randomly scattered) data grids. This software library was developed at NCAR.

Recommendation: Use REGRIDPACK for regridding purposes. For more general interpolation needs, use library FITPACK instead.
