how to save data in app designer then call back that data to use again?

3 views (last 30 days)
i have an app in app designer and it has two TABS tab one has questions to ask for quantities and tab 2 asks for times for each thing when you click done on tab one it takes the data from tab two and multiplies it by the quantity i want to save the times so that when you enter a time it stays that time every time the app is started so that you dont have to enter the time every time. Simplified if i enter red cars take 10 hours then every time i open the app it will have the red car variable by the quantity untill i update the time.
tab one
the equasions and quatnities
tab two
one of the values pulled to tab one... this is what i want to save

Hi,
One approach is that.
While closing the app, in the UIFigureCloseRequest callback, you can save all the required data in a .mat file
In StartupFcn, you can load the .mat file, get the required data and fill in the components.
