sll_f_new_lagrange_interpolation_1d()

type(sll_t_lagrange_interpolation_1d) function, pointer, public sll_m_lagrange_interpolation_1d::sll_f_new_lagrange_interpolation_1d	(	integer(kind=i32), intent(in)	num_points,
		real(kind=f64)	xmin,
		real(kind=f64)	xmax,
		integer(kind=i32), intent(in)	bc_type,
		integer(kind=i32), intent(in)	d,
		integer(kind=i32), intent(in), optional	periodic_last
	)

Parameters

[in]

periodic_last

periodic_last indicates if the input data repeats the first point at the end if we have periodic data. It takes the values 0 (not repeated) or 1 (repeated). Default : 1.

type(sll_t_lagrange_interpolation_1d), pointer

lagrange

)

This function computes the weights w_j for the barycentric formula.

Parameters

lagrange

lagrange is the lagrange interpolator object

sll_s_cubic_spline_1d_eval_array()

subroutine, public sll_m_lagrange_interpolation_1d::sll_s_cubic_spline_1d_eval_array	(	real(kind=f64), dimension(1:lagrange%nb_cell + 1), intent(in)	fi,
		real(kind=f64), intent(in)	alpha,
		type(sll_t_lagrange_interpolation_1d), pointer	lagrange
	)

This function computes the value at the grid points displacement by -alpha.

Parameters

	lagrange	lagrange is the lagrange interpolator object
[in]	alpha	alpha is the (negative) displacement
[in]	fi	fi are the values at the grid points
