Is it possible to import .mat files into AppDesigner?

I have created a Software GUI using App Designer. It however is computer intensive. To speed things up I would like the to import pre-calculated data using the specified inputs in the GUI. Is there any way of loading .mat files into App Designer?

Sure. You can insert a load() into your callback, at least to load data and objects.

If your intent is to load graphics objects, or design components (such as to load ui parts dynamically) then the answer might end up being different.

How do you then share that data with other functions in the app? In GUIDE, I would do the following inside my callback:

load mri
handles.mriDATA = mri

What is the equivalent in appDesigner?

You can add a property for each global variable that you need. For example, if you need the variable 'A', add a property for 'A' and then call in any function as 'app.A'

[Adi Purwandana]

what do you mean with add a property for A?

what if I want to call a variable from a mat file (there were many variables there)? i want to use this variable in next calculation within app designer. Thank you

here is my line:

[filename, path] = uigetfile({'*.mat', 'Text Files (*.mat)'});

data = load(filename); % inside this filename there were some variables, one of them: "longitude"

..... (?)

what I want is call a variable inside this .mat file (lets say "longitude").
