How can I use data from a .m file and use it in the appdesigner?

Some background: I have several files that all do different things but are connected with each other. They are either the testing code, a class or a subclass. In one of my files it essentially recieves all of the data from the testing code. I want all of the data from the data_retriver subclass to go into the app. However, I am stuck on how to take all of the data from the data_retriver subclass and essentially import it into the app designer. So how would one import data from a subclass into the app? Thank you for your help!

Can you call the function on startup of the GUI?

How would I go around doing that? so in the start up function on the app how would I call the function? I tried sim = (@data_retriver). That did not give me an error but I do not think it gave me of the values inside of file.

If it is a normal function you can call it as usual: sim=data_retriver;

I just tried that and it did not seem to work. the error was

"Invalid default value for property 'sim' in class 'app1':

Unrecognized function or variable 'data_retriver'. " data_retriver is a subclass. So in the data_retriver class it has several functions inside of it, for example, a function called RecordData(obj, drone). And in this function it takes in the drone subclass. In this drone subclass, it has like 10 functions that calculate the altitude, position north, position east, phi angle, psi angle, etc. So then back in the RecordData function it would extract those values at every time interval. so should I run the testing code and then send all of the data from the data_retriver (maybe this needs a new name) to the app?

How are you using it outside of the GUI? And where exactly did you try putting it?

[Nicholas Carreon]

So outside of the GUI, I am making a drone simulation. So in this simulation the drone will go up and and go through the designated flight path before descending at the of the flight path. During the flight path, the drone is locked onto a single point and as the drone moves a camera on the drone moves in order to keep focusing on the said target. Then after the simulation is complete, a video pops up and it shows the flight path and the camera moving through the flight path. All of this data is then stored in the data_retriver function for simpler access and readability.

I put the sim = data_retriver in the properties function.

Thank you for you help. I really do appreciate it.

Why did you put it in the properties section? You probably do need to create a property, but I expect you need to put the function call in the startup function. And I meant what exact code you are using.

[Nicholas Carreon]

YES! THAT IS EXACTLY IT! okay yeah it is working now! Thank you so much!!!!!
