real(dp) function	cspl_interp (xc, csp)
	Interpolates a function using previously calculated representation of splines.

Detailed Description

csplev Performs a spline interpolation in a point or in a table

See also: cspl_interp and cspl_interp_tab

Example:

  ! Create the CubicSpline
  ! Notice that we know exactly the second derivative
  call csplrep(x, y, -y(1), -y(ndim), csp)
  ! Apply the interpolation to the new grid
  ynew = csplev(xnew, csp)

Member Function/Subroutine Documentation

◆ cspl_interp()

real(dp) function cspl_interp	(	real(dp), intent(in)	xc,
		class(cubicspline), intent(in)	csp )

Interpolates a function using previously calculated representation of splines.

Note: Before calling this function, must be called csplrep()

Parameters

[in]	xc	value where evaluate the interpolation
[in]	csp	spline coefficients

Returns: the interpolated value

◆ cspl_interp_tab()

real(dp) function, dimension(size(xnew)) cspl_interp_tab	(	real(dp), dimension(:), intent(in)	xnew,
		class(cubicspline), intent(in)	csp )

Interpolates a function using previously calculated representation of splines. Works over an array of x values and returns an array of interpolated values
