MATLAB: How to launch a FreeFem++ (.edp) file from MATLAB 2018b

app designerfreefem++MATLABmatlab gui

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.

Please follow the steps as outlined by the arrows in the attached picture. Basically, what you should do is

1) Select the Design View AppDesigner

2) Select the Component Whose Id You Want To Know

3) The highlighted text under the app.UIFIGUREin the Component Browser pane is the full ID of the selected component.

So if you selected a button whose text is "Select File" then in the Component Browser under app.UIFIGURE, the text app.SelectFile will be full id of the selected component.

MATLAB: How to make an image file path relative to an mlapp file that uses it

When given a relative file path, MATLAB will search the current directory and then the MATLAB path. When the current directory is a folder containing both the .mlapp file and an image file, 'icon.png', calling "uiimage(app.UIFigure, 'ImageSource', 'icon.png');" finds the image, but if the current MATLAB directory is different from that folder then it won't be found unless it is on the MATLAB path. The absolute file path can be hard coded, but this makes the app difficult to share between users. Commands like "pwd" also return the path to the current MATLAB directory, and not the path to the directory of the script that called it.

To obtain the absolute path to the image at run time, the following lines can be added to "startupFcn" in the .mlapp file:

imageFile = 'icon.png';
absPath = fileparts(mfilename('fullpath')); % absolute path to the folder containing the mlapp file
imageAbsolute = fullfile(absPath, imageFile); % absolute path to the image file
uiimage(app.UIFigure, 'ImageSource', imageAbsolute);
