I want to collect data to cell array in Matlab App Designer.

Hi,
l am trying to make an app that takes some input from user and makes calculations, and then collects the data (in cell array or something).
After that, input boxes should set to zero to allow user to input other cases. My goal is collecting all the data from user, and allow user to get the result for a sepecific case if wanted.
I couldn't make the collection part for more than 1 case.
Thank you in advance.

Here is an app that collects data entered into two numeric editfields into matrix, and also performs some calculations and stores the results in a cell array.
To use:
- Enter some numbers.
- Hit the Save button to store the numbers, perform some calculations, store the results, and reset the editfields to 0.
- Hit the Done button to save all the data and results collected so far into a mat file and close the application.
Hopefully you can get some ideas about what to do with your real app from this simple app.
