Changing working directory in matlab to current script dir with running blocks

Question

Is there a way to change the current working directory to current script directory with running code just inside one block of script? Script folder is not added to path.

Redefined: Is there a way to to change the current working directory to script that's currently active in editor?

Solution 1

I found the solution (was looking in wrong direction before).

tmp = matlab.desktop.editor.getActive;
cd(fileparts(tmp.Filename));

Solution 2

You can use mfilename to get the current script name, cd(fileparts(mfilename)) should change to the correct directory.

If you frequently have to run scripts which need to be run in their script directory, you can use this function:

function varargout=run_in_dir(fun,varargin)
location=which(func2str(fun));
assert(exist(location,'file')~=0,'fun does not seem to be a m. file');
old_dir=pwd;
cd(fileparts(location));
try
if ~isempty(varargin)
    [varargout{1:nargout}]=fun(varargin{:});
else
    [varargout{1:nargout}]=fun();
end
catch ME
    cd(old_dir)
    rethrow(ME)
end
cd(old_dir)
end

To run sin(3) in the directory where sin is defined, use run_in_dir(@sin,3)

I think it is cd(fileparts(mfilename('fullpath')));

Unlike the solutions using mfilename, this one actually works when you're not running the command inside the file itself (or when executing a cell).

Or cd(fileparts(which(mfilename))) -- but only cd(fileparts(mfilename)) does not work.
