Cubic spline interpolation fortran
WebCubic spline interpolation is a mathematical method commonly used to construct new points within the boundaries of a set of known points. These new points are function values of an interpolation function (referred to as spline ), which itself consists of multiple cubic piecewise polynomials. Cubic spline interpolation in Fortran A module for cubic spline interpolation in Fortran, based on: spline.f spline.f90 , a Fortran 90 translation of spline.f Requirements A somewhat recent Fortran compiler ( gfortran is the default compiler in the Makefile ). Usage Usage looks like this: type (spline_t) :: spl !
