How can I launch a FreeFem++ (.edp) file from MATLAB 2018b?

Hello everyone,

I am working on Creating a GUI using MATLAB App Designer, the user will insert some inputs, click on Run, then some code is executed, then the output figure should appear.

My problem is that the code is executed by FreeFem++ software, so how can I embedd the code in the MATLAB, i mean when the button in the GUi is clicked, how can it automatically open the FreeFem (.edp) file and execute it?

Thank you.

In the ButtonPushed callback function, you can add the following line for executing a .edp file

system(['FreeFem++ ' path_to_file]); 

If you want to select a file interactively, you could also use the uigetfile function

[file, path] = uigetfile('*.edp'); 
selectedFilePath = fullfile(path, file) 
system(['FreeFem++ ' selectedFilePath]); 

Note: Make sure the folder names in your selectedFilePath do not have spaces.

Thank you so much.

Both methods worked with me but with a problem,

when I use these three lines:

[file, path] = uigetfile('*.edp'); 
selectedFilePath = fullfile(path, file) 
system(['FreeFem++ ' selectedFilePath]); 

after i push the button, the browser opens and i choose the file i want (i made sure there is no space in the names of the folder) then the code is executed and the FreeFem figure appears.

Until now everything is perfect.

However, after these three lines, I have some other lines that I need to execute as well, they aren't executed ! MATLAB is stuck at these three lines and doesn't exit, it keeps running the FreeFem code without exiting.

Same thing happens when I use the other method:

system(['FreeFem++ ' 'C:\Users\Lenovo\OneDrive\Desktop\Trial6\main.edp']); 

When MATLAB reaches this line, it executes the FreeFem code and the output FreeFem figure appears, but then the rest of the code isn't executed.

How can I solve this issue?

Thank you.
