In thomasblanchet/gpinter: Generalized Pareto Interpolation

First derivative of the quintic spline function

Description

First derivative of the quintic spline over an interval [x0, x1].

Usage

hd1(x, x0, x1, y0, y1, s0, s1, a0, a1)

Arguments

x	A number between x0 and x1, at which the function is evaluated.
x0	Lower bound of the interval.
x1	Upper bound of the interval.
y0	Value of the spline at x0.
y1	Value of the spline at x1.
s0	Slope of the spline at x0.
s1	Slope of the spline at x1.
a0	Second derivative of the spline at x0.
a1	Second derivative of the spline at x1.

Value
