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
