Functions

public function interpol1d(intorder, nnodes, dx, ui, x)

Performs a 1D polynomial interpolation

Arguments

Type	Intent	Optional	Attributes		Name
integer,	intent(in)			::	intorder	Interpoaltion order, yet only 1 and 3 ar available
integer,	intent(in)			::	nnodes	Number of nodes of interpolation data
real(kind=FP),	intent(in)			::	dx	Distance between nodes (equidistant)
real(kind=FP),	intent(in),		dimension(nnodes)	::	ui	Values of interpolation data
real(kind=FP),	intent(in)			::	x

Return Value real(kind=fp)
