## When to use the fzero command in MATLAB?

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. If the function is not continuous, fzero may return values that are discontinuous points instead of zeros.

## How to find the zero near 2 with fzero?

To find the zero near 2 z = fzero(@f,2) z = 2.0946 Because this function is a polynomial, the statement roots([1 0 -2 -5])finds the same real zero, and a complex conjugate pair of zeros.

**How to find zero of funnear x0 in MATLAB?**

Description x = fzero(fun,x0) tries to find a zero of funnear x0, if x0is a scalar. The value xreturned by fzerois near a point where funchanges sign, or NaNif the search fails. In this case, the search terminates when the search interval is expanded until an Inf, NaN, or complex value is found.

### How to create an array of all zeros in MATLAB?

X = zeros(sz1,…,szN) returns an sz1-by-…-by-szN array of zeros where sz1,…,szN indicate the size of each dimension. For example, zeros(2,3) returns a 2-by-3 matrix. X = zeros(sz) returns an array of zeros where size vector sz defines size(X). For example, zeros([2 3]) returns a 2-by-3 matrix.

### What kind of algorithm is the fzero command?

The fzero command is a function file. The algorithm, created by T. Dekker, uses a combination of bisection, secant, and inverse quadratic interpolation methods. An Algol 60 version, with some improvements, is given in [1].

**How to create vector of all zeros in MATLAB?**

If the size of any dimension is negative, then it is treated as 0. Beyond the second dimension, zeros ignores trailing dimensions with a size of 1. For example, zeros (3,1,1,1) produces a 3-by-1 vector of zeros. Data Types: double | single | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

## What are the arguments of the function fzero?

Arguments funis the function whose zero is to be computed. It accepts a vector xand returns a scalar f, the objective function evaluated at x. The function funcan be specified as a function handle. x = fzero(@myfun,x0)

## Which is the best version of the fzero command?

The fzero command is a function file. The algorithm, created by T. Dekker, uses a combination of bisection, secant, and inverse quadratic interpolation methods. An Algol 60 version, with some improvements, is given in [1]. A Fortran version, upon which fzero is based, is in [2].
