Polynomial

Calculating the value of a polynomial from the given coefficients.

$polynomial$

Description

The Polynomial block calculates the value of the polynomial at each calculation step for the input signal .

The block icon displays the degree of the polynomial, i.e. the number of polynomial coefficients specified using the Polynomial coefficients parameter minus one.

Ports

Input
