This example adds MATLAB® to the list of languages in this C++ vs Java vs Python vs Ruby: a first impression article (http://web.archive.org/web/20100420080552/http://www.dmh2000.com/cjpr/ ), which compares implementations of a Red Black Tree binary search algorithm (http://www.cs.auckland.ac.nz/software/AlgAnim/red_black.html ).
The side by side code comparison shows the same simple object oriented example written in C++, Java, Python, Ruby and MATLAB. The MATLAB implementation uses the new object oriented features available in R2008a. This example is designed to help programmers familiar with these other languages learn object oriented programming practices in MATLAB.
How to Compare the Languages
Click download, then save and unzip the files to a folder. Open the comparelanguages.html file. The code for two languages is displayed side-by-side in two frames. You select which two languages to compare by clicking on the links at the top of each frame. Note that, unlike most of the other languages, you cannot currently put more than one class in a single MATLAB class definition file, so a fake combined file with the two classes and the test function (that does not run) is used for the side-by-side HTML comparison. The MATLAB code is contained in the sub folder called MATLAB_Code. The equivalent C++, Java, Python and Ruby code was available from the dmh2000 web site.
Although this example does let you compare the object oriented syntax of these languages, it does not compare the languages' ability to develop technical computing applications such as for signal processing, image processing, financial modeling, etc, for which MATLAB is designed.

Verys useful. THanks :)
Why doesn't the matlab test function run ?
Yes, I agree that this is a pure translation / syntax comparison, intended to help programmers of these languages, become familiar with MATLAB OO syntax. It could be implemeted in a way more appropriate for MATLAB (while loosing the direct syntax comparison). I would encourage anyone to submit a new version of the code that does this. (I will fix the HTML typo - Thanks).
What Adrian said.
Handle behavior was not added to custom classes so that you could go around and translate C++ thinking into MATLAB!
For example, the NodeVisitor class is totally superfluous, and should just be a function (it has no data!). I also don't see why a MATLAB class would need a COPY method, it always exists implicitly through the assignment operator.
There is a </span> missing at the end of line 6 of the program in RBMATLAB.html, all the code is green!
Great non-trivial example! I know OO already so this was great for syntax, organization etc. Helped me out a lot!
want some detail info
Your effort is appreciated, but this comparison needs improvement. You've neglected to use language-specific idioms and techniques, making this into little more than a comparison of syntax. That's OK, but I believe the purpose of language comparisons is to highlight useful features. Programmers can write C++ code in any OO language, which seems to be what happened here.
i want to know matlab ODE program
i want to know ODE program.
Fantastic efforts, Congratulations!! Is it possible to send a CD compling all the demos for ready reference.
this matlab is very good
1) in the Matlab implementation, the NodeVisitor class is not anonymous. The comment in Line 229 should be changed.
2) getter and setter methods for val and color should be implemented (for encapsulation, so the class internals can later be changed without changing its users)
