With closures some OO functionality can be "emulated". The only problem is that everything has to stay in one m-file.

DiffPlug unleashes Simulink's potential.

What you are attempting is a non-trivial thing. I hate to be negative about this. I am not sure the student version comes with that, but that is really what you want. One of the most important lessons any programmer will learn is that each language has strengths and weaknesses. Trying to force a language into a paradigm it was not designed to be used for is an up hill battle, that will usually end with more crying then rejoicing.

I have just looked at doing MVC in Matlab and have come up with a pattern I think works will given the limitations of Matlab. The main problem is that GUI files are graphics object handles and not classes. However, if you wrap the GUI in a view class, you can subscribe to observable properties in a model class. You have to let go of using the handles structure in the GUI to store all your user data The good news is that Matlab classes support events and listeners quite well, including the observable properties I alluded to.

As far as I can tell, there should be no difference. If you forgo using GUIDE, then you have access to the entire figure, rather than a partial, so I wonder if that would open up any new possibilities to you. I can't think of anything; but would love to learn from your experience. Best, Chris. A really super example. I will be sharing this with the guys at work.

Wow, Awesome example. Thank you so much. This article has greatly accelerated my understanding of MVC. Don't know if you still track this blog but I have a two follow-up questions.

Would it be better more akin to MVC to call a function in the Controller class? I am under the impression that the View is "dumb" and the Controller "manages" the views; therefore it seems that we would prefer to keep the View and Model clean of any code that links the two.

Or should the Controller have a listener on the View? The former seems to make more sense to me but is there a preferred way per MVC? Thanks All, Adam. Hi Adam, Thanks for the kind words. I'm glad you found it useful. To me it makes sense that the view should 'listen' to the model, while the controller 'talks' to the model; but there are exceptions to every rule. So, I would answer your second question in the affirmative, i.

There may be other ways to construct the code, but this was the best one I could come up with given the constraints and allowances of Matlab OO design. Cheers, Chris. Some time ago I started to make use of Matlab's object oriented capabilities.

While I have been really pleased with the benefits of OO, I was struggling to figure out how to apply patterns to my program, specifically MVC. Well, last weekend I cracked that nut; and moreover, while watching the Grammys I made a little demo app to share. Model View Controller MVC is a compound pattern whose goal is to separate responsibilities into modular pieces that can be interchanged relatively easily.

If you didn't need a user interface, all you'd have to worry about is the model. Why should you have to burden the model with user interface code? Obviously you shouldn't, thus the model view separation. Introduction of a controller loosens the coupling between the model and the view and, if done well, allows the behavior of the system to be modified by replacing the controller with a different one.

The main one is that the user interface is not a class; rather, it is a handle graphics object. The good news is that it's not hard to work around.

Name case 'density' set handles. M with the given input arguments. So, the model notifies the view when its properties change.

The GUI sends requests to the controller in response to user interaction. The controller instructs the model to update. You would not want to use such a heavy solution for this simple model; but it doesn't take much more complexity for the benefits of MVC to shine through. The complete source code for this demo is available at Matlab Central File Exchange.Documentation Help Center. This example shows how you can use model statistics to determine the effect of a change on model complexity. Open the Simple Mechanical System example model.

The Simscape Statistics window opens, but it does not contain any data. If you open a model, and then open the Statistics Viewer before running the simulation, the statistics data is not available.

The Refresh button in the toolbar of the viewer window displays a warning symbol yellow triangleand a message at the top of the viewer window tells you to click the Refresh button to populate the viewer with data. Click the Refresh button. The Simscape Statistics window now displays an overview of the models statistics in a collapsed state. Click to expand all nodes. You can see that, after variable elimination, the model contains five continuous differential variables, no algebraic variables, no discrete variables, and no zero-crossing signals.

To limit the range of motion, add a Translational Hard Stop block to the model diagram, in parallel with the Translational Inertia and the Translational Damper blocks, as shown in the following figure. The revised model, after variable elimination, contains six differential variables and five algebraic variables.

This happened because you added a nonlinear block Translational Hard Stop. Therefore, the linear optimization that the solver initially performed on the model no longer applies.

A classification tree or compact classification tree created by fitctree or compact. Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value.

Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1, Value describing the display of treeeither 'graph' or 'text'. Alternatively, you can use fitcensemble to grow a bag of classification trees. Mdl is a TreeBagger model object. Trees stores the bag of trained classification trees in a by-1 cell array. That is, each cell in Mdl.

Trees contains a CompactClassificationTree model object. Boost an ensemble of classification trees using all measurements. Specify tree stumps as the weak learners. Mdl is a ClassificationEnsemble model object. Trained stores the ensemble of trained classification trees in a by-1 cell array. Trained contains a CompactClassificationTree model object. The graph shows a tree stump because you specified stumps as the weak learners for the ensemble.

However, this behavior is not the default for fitcensemble. By default, fitcensemble grows shallow trees for boosted ensembles of trees. To view tree t from an ensemble of trees, enter one of these lines of code view Ens.

Ens is a full ensemble returned by fitcensemble or a compact ensemble returned by compact. Bag is a full bag of trees returned by TreeBagger or a compact bag of trees returned by compact. To save tree in the Command Window, get a figure handle by using the findall and setdiff functions, and then save tree using the function saveas.

Select the If package exists, increment name to prevent overwriting check box. Selecting this option prevents overwriting the Web view files if you export multiple Web views from the same model.

Exporting the selected systems to a Web view creates several support files, as well as an HTML file for displaying the systems. In this example, you change the defaults for the naming of the files.

The Temperature Control Chart appears in the top level of the model, but you cannot open that chart in the web view to see its contents. By default, if you export a whole model to a Web view, the Model Viewer pane shows the whole model.

You can display specific systems in the Web view. For example:. The AC Control subsystem appears in the model viewer.
