fzero (MATLAB Function Reference)

The fzero command finds a point where the function changes sign. If the function is continuous, this is also a point where the function has a value near zero.

fzero. 找只有一個變數函數零的部份. Syntax. x = fzero(fun,x0) x = fzero(fun,x0,options) x = fzero(fun,x0,options,P1,P2,...) [x,fval] = fzero(.

Check this out arrayfun(@(i) fzero(@(x) minme(y(i),x),1),1:numel(y)).

There are several problems in your code: fzero tries to find a zero of the function supplied as first argument.

fzero can be used, so long as only one argument is being varied at a time. It is a lower-level function. fminsearch is nice and easy until you ...

First, fzero finds roots of nonlinear functions and should not be symbolic. If you have a polynomial you should use roots() function. If you ...

The fzero command is a function file. The algorithm, created by T. Dekker, uses a combination of bisection, secant, and inverse quadratic interpolation methods. Description · Examples · Input Arguments · Output Arguments

The classic advice is to use plot FIRST. That is, plot the function, looking for locations where a root would exist, and then throw fzero at ...

In this video tutorial, “Finding roots of nonlinear functions” has been reviewed and implemented using fzero in MATLAB.
