How can I set the folder from which the MatLab App-desinger function starts as the default workspace?

14 visualizzazioni (ultimi 30 giorni)
I have developed a program within the Appdesinger. However, the .mlapp can only be launched and run correctly if all functions and files have been loaded into the workspace previously. When double-clicking on the program, only a part is loaded and the app does not work.
Which settings do I have to configure so that all necessary files are loaded from the local directory when the app is started directly?
can I define a startup callback function that allows this ?

you can set paths to specific folders under properties...
properties (Access = public)
topLevelFolder = pwd;
% Get a list of all files and folders under the top level folder or user
% defined path
files = dir(topLevelFolder);
% Get a logical vector that tells which is a directory.
dirFlags = [files.isdir];
% Extract only those that are directories.
subFolders = files(dirFlags); % A structure with extra info.
% Get only the folder names into a cell array.
subFolderNames = {subFolders(3:end).name} % Start at 3 to skip . and ..
for i = 1:length(subFolderNames)
path = addpath(genpath(subFolderNames{1,i}));
You can also create startupFcn but it will run after createComponents(app).
function app = YourApp
% Create and configure components
% Register the app with App Designer
registerApp(app, app.FigureName)
% Execute the startup function
runStartupFcn(app, @startupFcn)
if nargout == 0
clear app
