derivative()

double umontreal.ssj.functions.MathFunctionWithDerivative.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 umontreal.ssj.functionfit.BSpline, umontreal.ssj.functionfit.SmoothingCubicSpline, umontreal.ssj.functions.AverageMathFunction, umontreal.ssj.functions.IdentityMathFunction, umontreal.ssj.functions.Polynomial, and umontreal.ssj.functions.ShiftedMathFunction.
