I have the R2017b student version of matlab. But a I have to use a P-code created under R2013a version. Can I downgrade to the R2013 a version?

I have seen contradictory information about this for Student licenses, and no information about this for Home licenses or MOOC licenses. It is known to be possible for the other (non-Trial) licenses.

(R2007b was the version where pcode become incompatible.)

The P-code standard did not change between the Matlab versions 2013a and 2017b as far as I know. Are you sure that the incompatibility concerns the P-file, or is one of the functions called from inside the P-file not contained in your Matlab installation? Providing a complete copy of the error message might reveal this detail.

Thanks for the answer (^_^).
Follows the error message:

obj.Listeners{end+1,1} = handle.listener( containerObj, findprop( containerObj, 'PixelBounds' ),

Error in uiextras.CardPanel (line 50)
obj = obj@uiextras.Container( varargin{:} );
Error in uiextras.TabPanel (line 51)

The code appears to make use of the GUI Layout Toolbox, https://www.mathworks.com/matlabcentral/fileexchange/47982-gui-layout-toolbox -- or to be more precise, the older version of it https://www.mathworks.com/matlabcentral/fileexchange/27758-gui-layout-toolbox
Possibly that toolbox is not installed in your newer version of MATLAB.

Vahid Khorasani: which MATLAB release are you using, and which version of the GUI Layout Toolbox do you have installed?

I've installed the older version of toolbox, but the problem still persists.

You would need the newer version of the toolbox for newer MATLAB.

More precisely:
These two versions are incompatible, and you should only have the correct version in your Matlab path, depending on your Matlab release.

I tried both, one at a time. Now, I uninstalled Matlab and then a reinstallation. With the https://www.mathworks.com/matlabcentral/fileexchange/47982-gui-layout-toolbox, worked properly.
Thank you very much!
