# When to use the fzero command in MATLAB?

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

## 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].
