Detailed Description

Represents a mathematical function whose \(n\)th derivative can be computed using derivative(double,int).

Member Function Documentation

derivative()

double derivative	(	double	x,
		int	n
	)

Computes (or estimates) the \(n\)th derivative of the function at point x.

For \(n=0\), this returns the result of umontreal.ssj.functions.MathFunction.evaluate(double).

Parameters

x	the point to evaluate the derivate to.
n	the order of the derivative.

Returns

the resulting derivative.

Exceptions

IllegalArgumentException

if n is negative or 0.

Implemented in BSpline, SmoothingCubicSpline, Polynomial, ShiftedMathFunction, AverageMathFunction, and IdentityMathFunction.
