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 x2 -
4x + 4. For more information,
see Create and Evaluate Polynomials.
