Matlab can't find my file .m

I am trying to do a home work, I have given a code to work on, but MATLAB can't find it's location.

Before you say anything about me posting useless question, yes I have tried to solve this myself using this forum.

At this point i have tried to copy paste the code to create new file, but that won't work as well.

p.s. I am no pro in using MATLAB.

It appears that you installed MATLAB to your user's directory, rather than the default Program Files directory (where most applications install on Windows PCs).

You should install MATLAB in the default directory, or possibly in a MATLAB folder on your main disk, but certainly not in a user directory that you then try to use for saving and manipulating your own files in. Application installation folders are usually protected for security and robustness reasons, so the fact that you are trying to work in an application installation directory is a sign of massive weakness and vulnerability on your PC. MIxing your personal data files and application files is a terrible idea.

By the way, this applies to all applications, not just MATLAB: in general they should be installed to your Program Files folder (or similar) and you should NOT be working in the installation folder (or any folder under it).

It looks like the filename of sampling_theory has an extra space at the end. Try renaming the file from "sampling_theory .m" to "sampling_theory.m".

I agree with your assessment. I'm guessing hovering over that red line on the right side of the Editor window, immediately below the red square, would indicate a Code Analyzer message complaining about that same issue.

When I created a file named "sampling_theory .m" and saved it the Editor showed a dialog warning that I wouldn't be able to run it unless I changed the name. That's another way to detect this type of issue.
