Fastest root finding method
WebRoot Finding • Problem statement: given a function f(x), find x such that f(x) = 0 • Common assumptions: f is continuous, differentiable (but typically dont assume much more - in particular, don’t assume linearity) • Can be in one variable, or a vector valued function f(x) = 0 (we’ll focus on the one variable case for the moment) WebSep 19, 2002 · The built-in Matlab root-finding function fzero is discussed in Section 6.6; since it is built in, you may find it convenient to use fzero. This is an example of a hybrid method, which combines the reliability of bisection with the speedy convergence of Newton-like methods. One of the methods fzero uses is the Secant Method, described in ...
