.Modelica_LinearSystems2.Math.Polynomial.evaluate

Information

Syntax

y = Polynomial.evaluate(p, x);

Description

Evaluate a polynomial p at a given Real abszissa value x.

Note

For this function, functions for the first and second derivatives are provided, so that the function can be seamlessly used e.g. in mechanical models.

Example

import Modelica_LinearSystems2.Math.Polynomial;

x = Polynomial.x();
p1 = -6*x^2 + 4*x -3;

Polynomial.evaluate(p1, 1);
// = -5.0
