I amtrying to write miltilanguage app and i would like to keep track of the user prefences. I would like to use a mat file to store the last options user selected and I would like to keep it in the installation folder. How can I read it?
AppFolder=pwd;
returns the intended address only if the App is run directly from the installation folder. If run using desktop link it returns the desktop address.
文件= matlab.apputil.getInstalledAppinfo;
[path,~,~] = fileparts(files(1).location)
throws either "Index exceeds the number of array elements (0)." when trying to access files(1).location when executed from Matlab command line or App Designer or "Cannot resolve matlab.apputil.getInstalledAppInfo" when executed from the standalone app.
How can I get the installation folder name to be able to store metadata neatly? Preferrably the way I can compile for Windows and linux without changing the code much.

我个人使用此函数来存储持久文件，而不管OS和运行时版本如何：GetWritable Folder.

I was able to resolve this with this solution:
[〜，结果] =系统（'path');
appDir = char(regexpi(result,'Path=(.*?);','tokens','once'));
Matlab的路径独立deskt补充道op app to the front system path on every session, so this function checks for the first entry on PATH. This worked really well for me.
