WebBrent’s method [1] is up to the task in all particulars. At any particular stage, it is keeping track of six function points (not necessarily all distinct), a, b, u, v, w and x,defi ned as … In numerical analysis, Brent's method is a hybrid root-finding algorithm combining the bisection method, the secant method and inverse quadratic interpolation. It has the reliability of bisection but it can be as quick as some of the less-reliable methods. The algorithm tries to use the potentially fast … See more The idea to combine the bisection method with the secant method goes back to Dekker (1969). Suppose that we want to solve the equation f(x) = 0. As with the bisection method, we need to … See more Brent (1973) proposed a small modification to avoid the problem with Dekker's method. He inserts an additional test which must be satisfied before the result of the secant method is accepted as the next iterate. Two inequalities must be simultaneously … See more • Atkinson, Kendall E.
