How to access properties of objects instantiated between different classes in multi-window matlab app designer

I'm creating an application where the main app, after performing some functions and storing some data, calls app.2 or app.aux. However, to perform a certain function in app.2 I need a result (artificial neural) created in the main app.´

The neural network is a public property in the main app

app.2 does not display the neural network created in the main app as properties when it starts. Can someone help me?

app2 and app aux each have constructor methods. Change the constructors to accept an option parameter which is the handle of the calling app. Then when you invoke them, pass in app from the first routine.

If it does not permit you to change the constructor, then have the constructor just create the new app and return its handle. Then add a method that accepts the handle to the calling app and stores it away and does whatever real work is desired.

Thanks a lot for the quick response.

I'm sorry please.

I'm a beginner in programming language and I'm from Brazil.

I'm still studying object-oriented programming and your answer should be correct, but it was too advanced for my understanding.

In the main app, or first window, the function is to provide data for the creation and training of an artificial neural network. Once created, the neural network loaded into properties (access = public).

In the aux app, or second window, I want the user to enter input data so that the network returns data simulated by the neural network. I would like the user to click the "Simulation" button to invoke the neural network created in the main app and simulate the data provided by the user. I try to invoke the calling app handle with "app.net_SOLD" in the mock button code, but the app aux doesn't recognize what "app.net_SOLD" means.

Should I use "app input arguments"?

What code could be used to

" % Callbacks that handle component events

methods (Access = private)

% Code that executes after component creation

function startupFcn(app, Calling)"

If you can help me I would really appreciate it!

If you need more information I can send it to you.

Thank you very much

I'll try to explain it better:

After training the neural network and creating it as app.net_SOLD in the main app (app_RNA), the "next step/simulate" button is activated and calls the aux app.

 % Button pushed function: PrximaetapaSimularButton
        function PrximaetapaSimularButtonPushed(app, event)
            app_RNA_2 (app);

In the aux app I inserted a new startupFcn function.

 % Code that executes after component creation
   function startupFcn(app, app_RNA, net_SOLD)

In the aux app I inserted a new startupFcn function.

My intention was to load the network created in the main app to the aux app. I don't know if I did it correctly.

I've already tried to put other programming codes, but I can't get the network created in the main app to be built (or recognized) in the aux app.

Hello

I finally got the code right.

I created a Calling property in app aux.

 properties (Access = private)
        Calling

And I started the app aux with the following code.

   % Code that executes after component creation
   function startupFcn(app, app_RNA, net_SOLD)
   app.Calling = app_RNA;  % carregar dados do app main

Then I inserted the following code in the "simulate" button

   app.D1 = [app.Is; app.Us; app.Vs; app.Es;]%with some error
   app.Simul = sim(app.Calling.net_SOLD,app.D1)

When the data is manually entered with the matrix D1= [170; 10; 8 ;6;] (for example), I get the simulated response by the neural network.

However, I'm having difficulties to assemble the D1 array, because it is assembled from the EditFieldNumeric buttons and when I assemble the array with the code.

   app.D1 = [app.Is; app.Us; app.Vs; app.Es;]

where app.Is.. app. Us.. are the values of the fields entered by the user, and the matrix D1 does not assemble an array and the error appears.

"Error using network/sim (line 248). Inputs is not a matrix or cell array."

I request a "test" button to send me the D1 matrix created by the numeric field data and I have the following response.

value =

4×1 NumericEditField array:

NumericEditField (170)

NumericEditField (10)

NumericEditField (8)

NumericEditField (6)

I would need the answer to be:

value =

170

10

8

6

Can you help me?

   app.D1 = [app.Is.Value; app.Us.Value; app.Vs.Value; app.Es.Value];
