The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

or can I write matlab code in C#.net environment ?

jaime_olivares:
You can't write matlab code in C#.net environment. I look at this issue frequently in my work.
Matlab is a modeling tool, not an implementation tool. Once you have tested your model, you have to rewrite your code in your desired implementation language (like C#)
Also you can use the Matlab compiler (mcc) to translate to C language, so it will be easier to translate to C#.
Have a look to: http://www.mathworks.com/access/helpdesk_r13/help/toolbox/compiler/appaqui2.html

thanks jaime_olivares,
but can you please publish the article of that link somewhere else or as attachment here ?
because, when I tries to open the link, it gives me access is denied.
thanks in advance.

try with http://www.mathworks.com/access/helpdesk_r13/help/toolbox/compiler/compiler.html

From matlab site:
"MATLAB Compiler can generate these kinds of source code:
C source code for building MEX-files.
C or C++ source code for combining with other modules to form stand-alone applications. Stand-alone applications do not require MATLAB at run-time; they can run even if MATLAB is not installed on the end-user's system.
C code S-functions for use with Simulink®.
C shared libraries (dynamically linked libraries, or DLLs, on Microsoft Windows) and C++ static libraries. These can be used without MATLAB on the end-user's system.
Excel compatible plug-ins
COM (Component Object Model) objects. "

Well, I am not a Matlab guru. Appears to be is a configuration problem, matlab is trying to locate a C++ compiler. Have a look to this article for more tips: http://www.codeproject.com/KB/cpp/mexFunction.aspx?df=100&forumid=23357&exp=0&select=1859439
and look at article comments below.

I have look to the article I helps for C++ compiler, It works for C++ but not for C#

yes, thats true, but it is far easier to convert from C++ to c# than mathlab to c#
