I am about to use the Matlab function 'heatmap' to display (visualize) data from within the Simulink simulation.
The data which are inputting this Simulink block are individual signals in continuous-time simulation. The Simulink block should form the "matrix (image)" and display it. I am using the Matlab function block from within Simulink where I am calling the heatmap function as follows
Unfortunately, I am not able to display the heatmap, how can I display the heatmap from within the Simulink model?
I am doing it this way - are there any other better options?

I have a MATLAB/Simulink software which is converted to C code, to be applied as an embedded application.
Inside this Simulink model I have a few stateflow with function call charts. These subsystems refer to some base workspace parameters to do their calculations, as follows:
Whenever I try to simulate this model, stimulating the inputs and reading the outputs, I get the following 'glitch' - the workspace defined variable 'multiplies', and the model simulation crashes because these new parameters have no defined values:
If I try to run the model again, more clones are created (4, 5 ,6 ...).
Do anyone has any clue on this?
Thanks!
Im using yii2 and php presentation to create powerpoint files.
The point is...
I have a ExportController that has data intructions to make data useful for phppresentation. But it also has grafic instructions to create files and download them.
So ExportController is huge bunch of lines because grafic intructions take a lot of code lines.
What I want to do is to split up grafic instructions from data instructions.
How can I send data from actionConsultar (it is ExportController) to actionGenerar (Im planning it to be in GraficsController).
If you know a better way to do this feel free to comment, all suggestions are welcome.
The right way is create a proper model and add common function to this model so you ca refer to the function in all the action of your controller passing simply the param data .. when you create and manipulate the model ..
A second useful way is based on a collection of helper function located in a common helper class.
You can define a proper area and assign the right namespace to you eg: GraphicHelper.php containing a class GrapichsHelper with the funcion you need so you can import this function simply adding a use GraficsHelper; when you need some function
There are multiple draw_if_interactive() expressions in the pyplot module but I can't find this function's definition anywhere in the module.
From intuition and readings, it's an easy guess that the function enables on-demand plotting but where can I read its definition? Thanks.
The function is actually in the backend code. The actual implementation depends on your backend. For example the function with the TkAgg backend is in backend_tkagg.py:
def draw_if_interactive():
if matplotlib.is_interactive():
figManager = Gcf.get_active()
if figManager is not None:
figManager.show()
Same kind of functions seem to be for other backends, they use the matplotlib.is_interactive to determine if this is an interactive session and then use the backend specific drawing commands to draw the image.
I have AdvancedDataGrid and I wanted to access dataProvider.getItemAt(i) in function in my view.
I'm not getting any errors nor warning and the code is compiling, but when I run this function I get this error:
Property getItemAt not found on mx.collections.HierarchicalCollectionView and there is no default value.
Why can't I do this? I saw some samples ane people was using this function.
This is how I call it:
var x:Object = _dg.dataProvider.getItemAt(i);
The AdvancedDataGrid's dataProvider is a generic object. That, basically, means the compiler will let any property/method access on it slide without issues.
The HierarchicalCollectionView does not have a getItemAt() method, which is why you get the runtime error. The Hierarchical collection, by nature, contains nested elements I'm not sure how you'd access a single element using a single index.
You probably want to use some form of getChildren() or getParentItem() method to get access to an individual node.
The places where you saw getItemAt() work were most likely using an ArrayCollection.
My good friend, Wikipedia, didn't give me a very good response to that question. So:
What are language bindings?
How do they work?
Specifically accessing functions from code written in language X of a library written in language Y.
Let's say you create a C library to post stuff to stackoverflow. Now you want to be able to use the same library from Python. In this case, you will write Python bindings for your library.
Also see SWIG: http://www.swig.org
In the context of code libraries, bindings are wrapper libraries that bridge between two programming languages so that a library that was written for one language can also be implicitly used in another language.
For example, libsvn is the API for Subversion and was written in C. If you want to access Subversion from within Java code you can use libsvn-java. libsvn-java depends on libsvn being installed because libsvn-java is a mere bridge between the Java programming language and libsvn, providing an API that merely calls functions of libsvn to do the real work.
Okay, now the question has been clarified, this isn't really relevant so I'm moving it to a new question
Binding generally refers to a mapping of one thing to another - i.e. a datasource to a presentation object. It can typically refer to binding data from a database, or similar source (XML file, web service etc) to a presentation control or element - think list or table in HTML, combo box or data grid in desktop software.
...If that's the kind of binding you're interested in, read on...
You generally have to bind the presentation element to the datasource, not the other way around. This would involve some kind of mapping - i.e. which fields from the datasource do you want to appear in the output.

In Flex (Actionscript 3). Source
A data binding copies the value of a property in one object to a property in another object. You can bind the properties of following objects: Flex components, Flex data models, and Flex data services.
The object property that provides the data is known as the source property. The object property that receives the data is known as the destination property.
The following example binds the text property of a TextInput component (the source property) to the text property of a Label component (the destination property) so that text entered in the TextInput component is displayed by the Label component:
<mx:TextInput id="LNameInput"></mx:TextInput>
...
<mx:Label text="{LNameInput.text}"></mx:Label>
Data binding is usually a simple way to bind a model to user interface components. For example, you have a class with a FirstName property. In flex you could easily bind that property to a textbox by setting the value of the textbox to {Object.FirstName}. Then, every time that FirstName property changes, the textbox will be updated without requiring you to write any code to monitor that property for changes.
Hope that helps.
