P-Code incompatibility!

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?

[Walter Roberson]

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.)

OMG... What now?

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:

No constructor 'handle.listener' with matching signature found.

Error in uiextras.Container (line 95)
            obj.Listeners{end+1,1} = handle.listener( containerObj, findprop( containerObj, 'PixelBounds' ),

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.

[Darby Lima]

Wow... maybe! Thank you very much! I'll try it!

[Vahid Khorasani]

Did not work!

[Walter Roberson]

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

[Darby Lima]

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

[Walter Roberson]

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

[Yair Altman]

More precisely:

• Matlab versions up to R2014a require https://www.mathworks.com/matlabcentral/fileexchange/27758-gui-layout-toolbox
• Matlab versions from R2014b onward require https://www.mathworks.com/matlabcentral/fileexchange/47982-gui-layout-toolbox

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

[Darby Lima]

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!

Thank you all for the comments, I solved the problem with the https://www.mathworks.com/matlabcentral/fileexchange/47982-gui-layout-toolbox

I also reinstalled matlab then the GUI. (^_^)
