pwl_interp_1d()

subroutine public interpolation::pwl_interp_1d	(	integer ( kind = 4 )	nd,
		real ( kind = dp ), dimension(nd)	xd,
		real ( kind = dp ), dimension(nd)	yd,
		integer ( kind = 4 )	ni,

Interpolates in 1D function.

Piecewise linear interpolation or extrapolation. Function is defined by discrete points. Subroutine can interpolate several points as once.

Parameters

nd	number of data points, must be at least 1
ni	number of interpolation points
xd	data points
yd	data values
xi	interpolation points
yi	interpolation values
nd	number of data points, must be at least 1
ni	number of interpolation points
xd	data points
yd	data values
xi	interpolation points
yi	interpolation values
