Trouble Passing Values In App Designer

2 views (last 30 days)
Hi, I have created a Double Dwell Cam Calculator in Matlabs App designer. The app is complete except for one item. I wish to export the profile of the cam, which is just a list of numbers, but a) am having trouble acessing the variable and b)have tried to initialize it prior to where it is used and setting it public using the "properties" drop down. Method b) has allowed the script to run with no errors and exports a text file, however, the text file is empty. Not only is the text file empty, the only place I can find it is in my workspace (that is a problem for a different post perhaps). Does anyone have an idea on how to fix this? The variable I wish to work with is "Cam_Displacement" which first appears on line 371. I try to export it to a text file on line 466. I have also tried to make it a global variable but that didnt help either. I cannot edit the function arguments either, they are grayed out. Any help would be appreciated! Thanks!!!

Hi Kyle,
Based on my understanding, you want to export Cam_Displacement variable into a text file. Changing Cam_Displacement to app.Cam_Displacement everywhere in the code except in its declaration resolved the issue. Attaching the updated code for your reference.
You can export matrices using writematrix function where the the path of the output file can be set in the second argument. A temporary workaround to edit function arguments would be copy the code in App Designer into a MATLAB file with the same name as name of the application. This lets you run the app from MATLAB editor.

Thank you so much! Sorry for such a delayed response, Covid and Grad school has been quite a distraction! This works great thanks again!
