Evaluating Polynomials. After entering the polynomial into MATLAB® as a vector, use the polyval function to evaluate the polynomial at a specific value. Use polyval to evaluate p ( 2). polyval (p,2) ans = 153. Alternatively, you can evaluate a polynomial in a matrix sense using polyvalm. The polynomial expression in one variable, p ( x) = 4 x ...

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.

Centering and scaling values, specified as a two-element vector. This vector is an optional output from [p,S,mu] = polyfit(x,y,n) that is used to improve the numerical properties of fitting and evaluating the polynomial p.The value mu(1) is mean(x), and mu(2) is std(x).
