PolynomialValue (FUN)¶

FUNCTION PolynomialValue : LREAL

This function block evaluates a given polynomial of arbitrary degree, \(p(x) = c_{n}x^{n} + c_{n-1}x^{n-1} + \dots + c_{1}x + c_{0}\) with \(c_{i} \in \mathbb{R}, n \in \mathbb{N_{0}}\) at a point \(x \in \mathbb{R}\) by use of the Horner scheme.

InOut:

Scope	Name	Type	Comment
Return	PolynomialValue	LREAL
Input	siDegree	SINT	degree of polynomial
	plr	POINTER TO LREAL	pointer to Array of polynomial coefficients; at first there is the coefficient of the monomial of highest degree (corresponds to \(c_{n}\) in the formula)
	lrValue	LREAL	point \(x\), where polynomial has to be evaluated
