subroutine	splevp (u, tck, y, der, ext, ier)
	splevp Computes a B-spline or its derivatives for a parametric spline. Given the knots and coefficients of a B-spline representation, evaluate the value of the smoothing polynomial and its derivatives. This is a wrapper around the FORTRAN routines splev and splder of FITPACK.

subroutine	splevc (x, tck, y, der, ext, ier)
	splev Computes a B-spline or its derivatives. Given the knots and coefficients of a B-spline representation, evaluate the value of the smoothing polynomial and its derivatives. This is a wrapper around the FORTRAN routines splev and splder of FITPACK.

Detailed Description

splev Computes a B-spline or its derivatives.

Given the knots and coefficients of a B-spline representation, evaluate the value of the smoothing polynomial and its derivatives. This is a wrapper around the FORTRAN routines splev and splder of FITPACK.

Examples:

  ! After setting data in x
  ! interpolate: (step one) Create interpolation and parameters u
  call splrep(x, y, tck=tck, s=s)
  ! interpolate: (step two) Apply to points u
  call splev(xnew, tck, ynew)

◆ splevc()

subroutine splevc	(	real(dp), dimension(:), intent(in)	x,
		type(univspline), intent(in)	tck,
		real(dp), dimension(size(x)), intent(out)	y,
		integer, intent(in), optional	der,
		integer, intent(in), optional	ext,
		integer, intent(out), optional	ier )

splev Computes a B-spline or its derivatives. Given the knots and coefficients of a B-spline representation, evaluate the value of the smoothing polynomial and its derivatives. This is a wrapper around the FORTRAN routines splev and splder of FITPACK.

Parameters

[in]	x	Points at which to return the value of the smoothed spline or its derivative
[in]	tck	A spline representation returned by splrep
[out]	y	Smoothed or interpolated spline values
[in]	der	The order of the derivative of the spline to compute (must be less than k).
[in]	ext	Flag controling the result for `x` outside the
[out]	ier	Flag given output status interval defined by the knot sequence.
