Raíces simbólicas. Raíces numéricas. La función roots calcula las raíces de un polinomio con una única variable representado por un vector de coeficientes. Por ejemplo, cree un vector para representar el polinomio x 2 − x − 6 y, después, calcule las raíces. p = [1 -1 -6]; r = roots(p) 3. -2.
Complex numbers x + i y can be dealt with “natively” in MATLAB®. This means that you can take powers and roots of any number. One surprising and very powerful fact about complex functions is that a single derivative (not a 2 × 2 Jacobian) gives you the full derivative information (assuming that the function is analytic).
MATLAB can find the roots of polynomials via the roots command. To find the roots of \ (z^2+6z+25\) you enter the coefficients of \ (z\) >> eqn = [1 6 25] . eqn = 1 6 25. and ask for the roots: >> roots(eqn) . ans = -3.0000 + 4.0000i. -3.0000 - 4.0000i. Notice that this is the same answer as given in the book.
