MATLAB: Mfilename not working on Live Editor

live editor

Hi. I'm using matlab 2016a. Inside a Live Editor script, I'm trying to get the script name, using the function mfilename, without any parameters, to get it. What matlab gives as an output is: MatlabEvaluationHelper.

I've tried to export this code to a classic matlab .m file, and seems to work fine. Any idea on what could be the problem? Thanks in advance

Hello Jaime,

I am afraid that mfilename does not function inside live scripts or functions. Our developers are aware of this feature request, and are considering possible resolutions for future releases of MATLAB.

Can you describe what you are trying to accomplish with "mfilename"? There may be other ways to get a similar workflow to what you desire.

Here is a cheat:

function open_local_mlx(mlxname, lineNum)
    whence = mfilename('fullpath');
    [filedir, basename] = fileparts(whence);
    mlxname = fullfile(filedir, [mlxname '.mlx']);
    matlab.desktop.editor.openAndGoToLine(mlxname, lineNum);
end

This must be put into the same directory that the target .mlx file is in, and this must be a .m (not a .mlx)

Now, in the .mlx that is to contain the link, insert a hyperlink that has a target

matlab:open_local_mlx('NAMEOFMLX', LINENUMBER)

where NAMEOFMLX should be just the basic name without extension, and LINENUMBER should be the absolute line number as given by the Live Script editor. This would have to be a non-markup line -- not a section break or text area or equation. But it can be a comment line.

It is also possible to go to a particular position within a particular line, using some deeper techniques.

I would not be surprised if there is a way to search for some particular text, but I have not happened to see that yet.

No, it is not possible at this time.

Live Editor does not use simple text files like the main MATLAB editor does: a .mlx file is a zip'd directory containing a number of items including XML files.

MATLAB Function Blocks do not reference .m files. It is not simply a header block together with the name of a .m to invoke, so it is not a simple matter of changing to parsing to permit referencing .mlx files as well.

Instead, MATLAB Function Blocks store the code as one of the properties of the block, inside a XML file, with .slx files turning out to be a zip'd directory containing (mostly) XML files. The Simulink block structure itself would have to be altered to permit Live Editor code.

... This should not be interpreted as "It is not going to happen": this should be understood as "It has not happened as yet, and there are complications that make it tricky to implement, so it might take a while."
