@Malaa Mansour

I reformatted your code for you, as it was unreadable.

Why do you have the "1" by itself after calculating n_error ?

Why do you have the line

Problem 1.1

which will attempt to invoke a function named Problem with character vector input '1.1' ?

What does this have to do with the Question about converting C++ code to MATLAB ?

yes you can! I am not going to ellaborate the whole process. you jst go on this link and you'll get soplution............. better y follow this link:-----------

Doesn't Coder translate Matlab to C++, not the other way around (C++ to Matlab)?

Answer 2

[Attaullah Shafiq]

create a MEX file via MATLAB Coder (using MATLAB Coder on a simple M file that just calls the C++ function using coder.cinclude and coder.ceval)
