How can I change the current folder to folder of .m file in my code.
Possibly with cd command
Or any command I can indicate that my excel file is in same location as .m file.
e.g. code.m path folder\My excel file.xls

Here's some code I got from Brett Shoelson of the Mathworks:
% Change the current folder to the folder of this m-file.
if(~isdeployed)
cd(fileparts(which(mfilename)));
end
Edit: Note that the isdeployed is important if you will be compiling and deploying your application. This let's it operate both for you, as the developer, and for your deployed application where it will skip the cd because doing cd like that in a deployed app can wreak havoc. If you won't be doing compiling, then you can do just the cd without the if.

This command that ran fine in my MATLAB R2015b, is not actually working in the newest R2022a!
EDIT:
Actually find the solution in an other answer
% Change the current folder to the folder of this m-file.
if(~isdeployed)
cd(fileparts(matlab.desktop.editor.getActiveFilename));
end

For live scripts, @Qi Wang suggested using this:
fileparts(matlab.desktop.editor.getActiveFilename)
to get the full path of the active live script file.

This works, but the problem is that most people expects code in .m file to work in .mlx and viceversa.
I think that this issue should be adressed by MATLAB's guys.
Best regards,
Javier

mfile_name = mfilename('fullpath');
[pathstr,name,ext] = fileparts(mfile_name);
cd(pathstr);

cd(which(fileparts('/path/to/your/file.m')))
