root of function in matlab

To compute the root of the function in Matlab, you can use the "fzero" function. The "fzero" function finds a zero of a given function near a starting point.

Here's an example code snippet:

main.m
% Define the function to find the root of
f = @(x) x.^2 - 2;

% Find the root of the function near the starting point of 1
x0 = 1;
root = fzero(f, x0);

In this example, we define the function f(x) = x^2 - 2. We then use the fzero function to find the root of the function near the starting point of x=1. The fzero function returns the value 1.4142, which is the square root of 2.
