Return fi, the interpolation of the original set of ns data
f @ s onto a target grid si of size nsi. Not-a-knot BCs are
applied.
integer, parameter :: r8=selected_real_kind(12,100)
integer, intent(in) :: ns number of input data points
real(r8), intent(in) :: s(ns) original grid
real(r8), intent(in) :: f(ns) the function values at s
integer, intent(in) :: nsi number of output data points
real(r8), intent(in) :: si(ns) the target grid
real(r8), intent(out) :: fi(ns) the interpolated data
Return fi, the interpolation of the original set of nt1 data
f @ t onto a target grid ti of size nti1. Periodic BCs are
applied: f(nt1) = f(1).
integer, parameter :: r8=selected_real_kind(12,100)
integer, intent(in) :: nt1 number of input data points
real(r8), intent(in) :: t(nt1) original grid
real(r8), intent(in) :: f(nt1) the function values at t
integer, intent(in) :: nti1 number of output data points
real(r8), intent(in) :: ti(nti1) the target grid
real(r8), intent(out) :: fi(nti1) the interpolated data
