Σc i u i y u Polynomial Polynomial Icon

Mathematical.Polynomial

Polynomial evaluation block (up to cubic).

Evaluates polynomial: y = c0 + c1u + c2u^2 + c3*u^3

Arguments: c0 - Constant term c1 - Linear coefficient c2 - Quadratic coefficient c3 - Cubic coefficient

Usage

PrimitiveComponents.Mathematical.Polynomial(c0=0.0, c1=1.0, c2=0.0, c3=0.0)

Parameters:

NameDescriptionUnitsDefault value
c0Polynomial coefficients [c0, c1, c2, c3]–0
c1–1
c2–0
c3–0

Connectors

  • u - This connector represents a real signal as an input to a component (RealInput)
  • y - This connector represents a real signal as an output from a component (RealOutput)

Behavior

\[ \begin{align} y\left( t \right) &= \mathtt{c0} + \mathtt{c1} u\left( t \right) + \left( u\left( t \right) \right)^{2} \mathtt{c2} + \left( u\left( t \right) \right)^{3} \mathtt{c3} \end{align} \]
