Hello! I have three files, 'originFile' which contains file1 and file2 , I would like to know how can I force Matlab to save the output files from funct1 in file1 into file1 and not in the 'originFile' ?! Thank you!

This depends on how you are writing it exactly, but every writing function I know of accepts explicit paths (i.e. full paths, including the drive letter).
A more specific answer is not possible, as you told nothing of how your code works.
Hi @Rik Wisselink, my code is spreaded out into two files file1 and file2 within each file there is some functions calling each other, and for organization purposes I would like to save the output files from functions in file1 in that same file. Thank you!

You can get the filename and name of the current function with dbstack:
ST = dbstack('-completenames');
ST =
file: 'C:\myProject\myfile.m'
name: 'myfile'
line: 2
If you have multiple functions (which will almost always be the case), ST will be a struct array, so ST(1).file would be what you need.
As a last remark: you must have an interesting function structure if subfunctions in one file can access subfunctions in another file. But that is your decision to make of course.


thank you for your reply I appreciate it! could you please explain your remark, I don't get it. Thank you!

(If my answer solved your question, please mark it as accepted answers.)
Normally, if you have a subfunction in a file, functions outside of that file can not call that function. You can circumvent this with something like fh = str2func(fid);[varargout{1:nargout}] = fh(varargin{:});
In short, I can't really imagine a function structure that makes sense and works the way you describe.
Hello, I just wanted to add another alternative that worked for me for those who might face the same problem. I have added to the function funct1 ,which I would like to get its out put , the following code line:
