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

How can I write a Level-2 MATLAB S-Function where the input and output

 How can I write a Level-2 MATLAB S-Function where the input and output might have unknown dimensions, or even be variable-size signals?

 

I need to write a Level-2 MATLAB S-Function where the input and/or output dimensions are unknown, and might also change during simulation.
 
Specifically, I would like to implement the two following scenarios:
 
A) Input: 1-D array of unknown fixed size. Two outputs: sorted array, and sum of all the elements.
 
B) Same as A), but the size of the array might vary during simulation.

A)
 
In the setup function of your MATLAB S-Function, you need to configure port properties to be inherited or dynamic:
 
>> block.SetPreCompInpPortInfoToDynamic;>> block.SetPreCompOutPortInfoToDynamic;
 
You can then override the only properties that you known, as for example:
 
>> block.InputPort(1).DatatypeID  = 0;>> block.InputPort(1).Complexity  = 'Real';>> block.InputPort(1).DirectFeedthrough = true;
 
>> block.OutputPort(1).DatatypeID  = 0;>> block.OutputPort(1).Complexity  = 'Real';>> block.OutputPort(2).Dimensions  = 1;>> block.OutputPort(2).DatatypeID  = 0;>> block.OutputPort(2).Complexity  = 'Real';
 
Note how the field 'Dimensions' has not been set for InputPort(1) and OutputPort(1).
 
B)

What are some good alternatives to Simulink?

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
