can anyone help me? I need the code.

What have you tried so far?

 doc solve
 doc fsolve

[Pelin]

our teacher didn't teach us matlab. he said you can learn by yourself but i don't know anything about it. i just know a little c++.

[José-Luis]

I would recommend you to read the Getting started part of the documentation. Few contributors are willing to do your work for you. Most are happy to help you understand Matlab. The two functions I suggested might be used to solve the problem, and the documentation comes with examples on how to use them.

I want to understand, too. I watched some videos about matlab but I was confused. I'll try to understand again. Thank you for your suggestions :)

Here's a simple example similar to ones given in the documentation for FZERO

>> fzero(@(x) x^2-1, 2)

ans =

       1

To solve

 x+cos(x)=0

write and save this function (myeq.m)

function f=myeq(x)
f=x+cos(x)

then call in matlab command

 x0=0
 sol=fsolve(@myeq,x0)
