How to save and load neural network created using Matlab designer app?

Hello

I'm using neural networks in the designer app developed for the welding area. The application creates and trains a network with user-supplied data.

How can I save the created network in the app after creation?

And after saving the neural network, should I use startupFcn for the application to load the saved network?

Finally, to load other networks saved in the workbook, which command should I use?

I've already tried the save net commands and the load command and the following message appears:

I believe the saved networks is in file 'mat' format, but I don't know how to save or load.

Can someone help me?

oops

I forgot to indicate the error message when I use the save command:

"Warning: Unable to save App Designer app object. Save not supported for matlab.apps.AppBase objects."

I see that a file with a ".mat" extension appears but I can't load it or verify its information.
