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. Functions Topics

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.

Polynomials in Matlab Polynomials • f(x) = anxn+ a n-1x n-1 + ... + a 1x + a0 • n is the degree of the polynomial • Examples: f(x) = 2x2-4x + 10 degree 2 f(x) = 6 degree 0 Polynomials in Matlab • Represented by a row vector in which the elements are the coefficients. • Must include all coefficients, even if 0 • Examples 8x + 5 p = [8 5]

Polynomial coefficients, specified as a vector. For example, the vector [1 0 1] represents the polynomial x 2 + 1, and the vector [3.13 -2.21 5.99] represents the polynomial 3.13 x 2 − 2.21 x + 5.99. For more information, see Create and Evaluate Polynomials. Data Types: single | double Complex Number Support: Yes

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 ...

p ( x ) = p 2 x 2 + p 1 x + p 0 .
