MATLAB: Save Live Script automatically as PDF

live script

Hello everyone,

I have a problem!

I wrote a program for the calculation of test data in the App Designer. The test results of the test person should be given to them in a report. Since I do not have access to the report generator, I have compiled the results in a live script and output them. I have set the button on the right to "hide code" and to save I press "save" and then "export to pdf".

Since I would like to compile the program as a standalone program, I cannot press the buttons myself and save the live script as a PDF.

I already tried the following:

matlab.internal.liveeditor.executeAndSave (which ('Handout.mlx'));
matlab.internal.liveeditor.openAndConvert ('Handout.mlx', 'test.pdf');

Unfortunately, the code is always displayed there! But the design fits 🙂

Is there another way to automatically save the LiveScript as PDF without code?

Hi Jana,

Thanks for using the Live Editor!

Actually, your workflow is expected to work. Unfortunately, there is a known issue that the 'Hide Code' state is not reliably stored with the document when no other edit opereation is made. We're working on fixing that bug.

As a workaound, you should try again to switch to Hide Code View and additionally make another change to the document. E.g. type a charachter and delete it. Then save. If you now close and reopen the Live Script, it should appear in 'Hide Code' mode.

With that, openAndConvert should export it properly without code.

Btw, I strongly recommend to not use openAndConvert and executeAndSave! Those functions were made for internal purposes and can be changed or removed at any time. Furthermore, they're not bullet-proof tested and may behave unexpectedly or wrongly.

However, since you're using it anyway, there is another solution for your worklfow. You can call

matlab.internal.liveeditor.openAndConvert ('Handout.mlx', 'test.pdf', 'HideCode', true);

With that additional argument, it always exports without code, regardless of the state of the document.

Again, be careful with using openAndConvert. Don't rely on its stability or existence in upcoming releases,

We're actively working on a public and well documented API to export Live Scripts programmatically. Stay tuned.

I hope, some of this helps.

Kind regards

MATLAB: Programmatically run and export live script

Hi, I'm late to the party, but I spent hours and hours on this issue, and by pure luck I just found the answer. So in hope someone reads this, here is the function you are looking for. It certainly is the one called by the "Save As" button.

doc matlab.internal.richeditor.openAndConvert

Best regards.

MATLAB: Can’t I find the “openAndConvert” function

There is an "openAndConvert" function packaged with LiveEditor and shipped with MATLAB. However, it is not clear from this description whether the "openAndConvert" function that your code depends on is the built-in MATLAB function or a custom function that you have written that shares the same name.

Assuming it is the built-in MATLAB function,

1. To locate the directory in which the file resides, please enter the following command:

which matlab.internal.liveeditor.openAndConvert

in the MATLAB Command Window. The output of this command gives the location of the file.

2. To get more information on the working of "openAndConvert", please enter the following command

help matlab.internal.liveeditor.openAndConvert

in the MATLAB Command Window.

If it is indeed the MATLAB built-in function, importing the file will resolve the issue you are facing. To import the function, please include the following command in the custom code.

import matlab.internal.liveeditor.openAndConvert

If this is instead a function that you have written that shadows the built-in function, you will need to figure out where you saved that function file and import it.
