Matlab question in complicated way..

Question

Let "f(x) = x^2 +x - 960"

Write a MATLAB script that finds a root of the user-defined function using bisection method and gives the tabulated results in a .txt file.

How can I solve this pleae ?

Answer 1

If you are writing a code with user-defined input, you should use a Matlab function (instead of just a script). You might try something like:

function root = my_fun(input_fun,x0)

%your code goes here

end

,where x0 is the initial guess, and input_fun is a function handle.

To give the tabulated results in a .txt file (assuming the results are the approximate roots for each iteration), you can explore the writematrix function.
