How do I access a MATLAB UI function in another .m file?

  I am attempting to declutter my MATLAB app code by separating some of the initialization into separate .m files. For this I have set up various files for each type of component (e.g. a file for buttons, graph, etc.). I am attempting to access a function in my master initialize file from the file for buttons. My code goes as follows in the buttons .m file goes as follow:   classdef buttons < handle methods %initializes the UI function buttonCreate(app) %Create file load 1 app.fileload1 = uibutton(app.gridLayout, 'push'); app.fileload1.FontSize = 36; app.fileload1.Layout.Row = [8 9]; app.fileload1.Layout.Column = 1; app.fileload1.Text = 'Load 1'; %proceeds to create the rest of the buttons end end end Now I attempt to access the  buttonCreate()  function in my master initialize file  initialize.m :   classdef initialize < handle prop

No appropriate method, property, or field 'Files' for class 'augmented?ImageDatas?tore'.

 Hi,

I am trying to apply "Train Deep Learning Network to Classify New Images". I did test exactly according to
https://www.matlabsolutions.com/documentation/deeplearning/train-deep-learning-network-to-classify-new-images.php
 
But I always got some problem as:
 
"No appropriate method, property, or field 'Files' for class 'augmentedImageDatastore'.
 
Error in googlenetJIAGUI (line 88)
valFrequency = floor(numel(augimdsTrain.Files)/miniBatchSize);"
 
When I ran:
 
 
%Train Network
pixelRange = [-30 30];
scaleRange = [0.9 1.1];
imageAugmenter = imageDataAugmenter( ...
    'RandXReflection',true, ...
    'RandXTranslation',pixelRange, ...
    'RandYTranslation',pixelRange, ...
    'RandXScale',scaleRange, ...
    'RandYScale',scaleRange);
augimdsTrain = augmentedImageDatastore(inputSize(1:2),imdsTrain, ...
    'DataAugmentation',imageAugmenter);


augimdsValidation = augmentedImageDatastore(inputSize(1:2),imdsValidation);

%Specify the training options. 
miniBatchSize = 10;
valFrequency = floor(numel(imdsValidation.Files)/miniBatchSize); %%valFrequency = floor(numel(augimdsTrain.Files)/miniBatchSize);
options = trainingOptions('sgdm', ...
    'MiniBatchSize',miniBatchSize, ...
    'MaxEpochs',6, ...
    'InitialLearnRate',3e-4, ...
    'Shuffle','every-epoch', ...
    'ValidationData',augimdsValidation, ...
    'ValidationFrequency',valFrequency, ...
    'Verbose',false, ...
    'Plots','training-progress');

I check inside of "augimdsTrain", there is no "Files". When I replace with the "valFrequency = floor(numel(augimdsTrain.Files)/miniBatchSize);" with "valFrequency = floor(numel(imdsValidation.Files)/miniBatchSize)" . "valFrequency = floor(numel(augimdsTrain.Files)/miniBatchSize);" It seems to work.

Hack way:
 
 
old_warning_state = warning('off', 'MATLAB:structOnObject');
temp = struct(augimdsValidation);
warning(old_warning_state);

valFrequency = floor(numel(temp.DatastoreInternal.Files)/miniBatchSize);

What are some good alternatives to Simulink?

Get MATLAB projects with source code for your learning and research. SIMULINK is a visual programing environment specially for time transient simulations and ordinary differential equations. Depending on what you need there are plenty of Free, Libre and Open Source Software (FLOSS) available: Modelica language is the most viable alternative and in my opinion it is also a superior option to MathWorks SIMULINK. There are open source implementations  OpenModelica  and  JModelica . One of the main advantages with Modelica that you can code a multidimensional ordinary differential equation with algebraic discrete non-causal equations. With OpenModelica you may create a non-causal model right in the GUI and with
