Hi Francois,
I understand that you are trying to get certain variables from MATLAB App Designer to the base workspace.
1. Since there are multiple variables to be exported, you can save the variables in a MAT file and then load it into the base workspace:
% In MATLAB App Designer
save("userInputData.mat"," Roi_cam1"," Roi_cam2"," Roi_cam3")
% In the script
load("userInputData.mat")
Here is the relevant section of the “save” function documentation:
2. Another way is to use the “assignin” function to save a variable to the 'base' workspace:
assignin('base', 'Roi_cam1', Roi_cam1)
More details are available on the documentation page for “assignin”:
You may refer to the following relevant MATLAB Answers thread too:
I hope this helps!
