Polynomials are equations of a single variable with nonnegative integer exponents. MATLAB ® represents polynomials with numeric vectors containing the polynomial coefficients ordered by descending power. For example, [1 -4 4] corresponds to x 2 - 4x + 4. For more information, see Create and Evaluate Polynomials.

Rational models are defined as ratios of polynomials and are given by. where n is the degree of the numerator polynomial and 0 ≤ n ≤ 5, while m is the degree of the denominator polynomial and 1 ≤ m ≤ 5. Note that the coefficient associated with xm is always 1. This makes the numerator and denominator unique when the polynomial degrees ...

[r,p,k] = residue(b,a) finds the residues, poles, and direct term of a partial fraction expansion of the ratio of two polynomials, and , of the form.

Aug 05, 2016 · Suppose I have a Matlab expression consisting of a ratio of polynomials of the symbolic variable 'x'. The polynomial coefficients are likewise symbolic. Is there a simple way to extract the numerator and the denominator of the expression? It is fine if the function returns either the polynomials or their coefficients.

This MATLAB function finds the residues, poles, and direct terms of a partial fraction expansion of the ratio of numerator and denominator polynomials, b and a.

Yes there is. If you search google "MATLAB symbolic numerator denominator" the following documentation appears: numden [N,D] = numden(A).

A SISO continuous-time transfer function is expressed as the ratio: G ( s ) = N ( s ) D ( s ) , of polynomials N ( s ) and D ( s ) , called the numerator and denominator polynomials, respectively.

Rational models are defined as a ratio of polynomials as given by: y = p 1 x n + p 2 x n − 1 + ... + p n + 1 x m + q 1 x m − 1 + ... + q m where n is the degree of the numerator polynomial and m is the degree of the denominator polynomial.
