Rusty FITPACK
Rusty FITPACK provides the 1D routines for spline interpolation and fitting
in Rust. The functions are translated from the original Fortran77 code FITPACK by Paul Dierckx.
This packages provides almost the same interface as the SciPy wrapper for FITPACK.
In concrete terms, the package implements five functions, splrep
, splev
, splder
and splev_uniform
as well as splder_uniform
.
