Rational models are defined as ratios of polynomials and are given by. y = ∑ i = 1 n + 1 p i x n + 1 − i x m + ∑ i = 1 m q i x m − 1. 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.

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.

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.
