Hi,

I have created one app which takes input as a path and if you press the button it loads specific .mat file from that path.

This is how app looks like

When I run .exe / standalone app , it gives following error in cmd.

'Error using matlabpath

Modifying the search path is not supported by MATLAB Compiler. Remove functions that modify the search path from your MATLAB code. To make files visible to your deployed application, add the parent folder to your MATLAB session.'

How to get ride of this issue ? or is it not possible in standalone app ?

this is how main part of code look like

Hi

You should not use the 'addpath' command (static) while creating the standalone executable file. Instead you can the get the directry information using uigetdir() as a dynamic. It avoids the error.

Thanks Gopinath .

Then how can I use uigetdir() to change the working dictionary to that path ?

Goal Is : I want to load specific .mat file which is there at that path location

Gopinath Karuppannan 2021-9-1

uigetdir() --> it allows the user to select the working directory and return the path of the folder. So you can save the path in variable.[link:https://in.mathworks.com/help/matlab/ref/uigetdir.html]. Refer the following example:

pathname = uigetdir();

dir(fullfile(pathname,'*.mat'));

Hope it helps.
