s_compute_finite_difference_coefficients()

subroutine m_finite_differences::s_compute_finite_difference_coefficients	(	integer, intent(in)	q,
		real(wp), dimension(-local_buff_size:q + local_buff_size), intent(in)	s_cc,
		real(wp), dimension(:,:), intent(inout), allocatable	fd_coeff_s,

		integer, intent(in)	fd_number_in,
		integer, intent(in)	fd_order_in,
		type(int_bounds_info), intent(in), optional	offset_s )

Compute the centered finite-difference coefficients for first-order spatial derivatives in the s-coordinate direction (x, y, or z). Supports up to 4th order accuracy.

Parameters

fd_coeff_s	Finite-diff. coefficients in the s-coordinate direction
fd_number_in	Finite-difference number
fd_order_in	Finite-difference order of accuracy
offset_s	Optional offset bounds in the s-coordinate direction
