Hi folks,
I have an App running on Web App Server. What I'm trying to do is read in a .mat-file and set some values depending on the file.
My aim is to get to a point where a user can make some changes on the GUI/app then save the entered values to a custom .mat-file and load them back into the app to a later point in time. I hope my problem is okay to understand.
If I run my App out of Matlab save/load works fine. But on the deployed app on the server it doesn't.
I get the following messages in the log of the server:
% saveload.mat is uploaded successfully
% Error using load
% Unable to read file 'saveload.mat'. No such file or directory.
What am I doing wrong?

Great! Also, don't use cd, rather supply full or relative path to load function. It is slow and can cause issues.

The solution is quite simple:
[file,path] = uigetfile('*.mat'); % see matlab documentation of uigetfile
cd(path)
data = load(file);

Hi, what if I don't want to have the dialog box open? I've already uploaded the .mat file as the supporting file when packaging the APP. Is this a way that I can directly code into the app so the web server automatically detects the .mat file on the web server path and load it?
Put it anothe way, when uploading the .mat file as the supporting file, what is the web server path where the .mat file gets stored?
