create a function that will perform secant method without the use inputting the derivative and with 10 iterations in matlab

To create a function that performs the secant method without the user inputting the derivative and with 10 iterations in MATLAB, you can follow these steps:

  1. Define a function for the equation you want to find the root of. Let's call this function f:
main.m
function y = f(x)
    % Define the equation here
    y = x^2 - 4;
end

  1. Create a function for the secant method, let's call it secantMethod:
main.m
function root = secantMethod(x0, x1, iterations)
    for i = 1:iterations
        % Calculate the next guess of the root
        x2 = x1 - f(x1) * ((x1 - x0) / (f(x1) - f(x0)));
        
        % Update the values for the next iteration
        x0 = x1;
        x1 = x2;
    end
    
    root = x1;
end

  1. Finally, call the secantMethod function with the initial guesses and the number of iterations desired:
main.m
x0 = 1; % Initial guess 1
x1 = 2; % Initial guess 2
iterations = 10;
root = secantMethod(x0, x1, iterations);
fprintf('Root: %.6f\n', root);

6 lines

This will perform 10 iterations of the secant method using the initial guesses (x0 and x1) and calculate the root. Adjust the f function to match the equation you want to find the root of.
