\"Blogger,By Guy Rouleau<\/a>

\r\n\r\n\r\nIn a previous post, I introduced the Embedded MATLAB Function block<\/a>. This block gives the possibility to write an algorithm in MATLAB code, include it in a Simulink model, and generate embedded C code using Real-Time Workshop.<\/p>\r\n\r\n

When seeing this, some users, especially from the signal processing and communication domain asked: Do I really need Simulink to generate embedded C code from a MATLAB function?<\/p>\r\n\r\n

To answer this question, I would like to highlight a webinar and a submission on the MATLAB Central File Exchange<\/a> from my colleague Houman Zarrinkoub<\/a>:<\/p>\r\n\r\n

Webinar:<\/strong> MATLAB to C Code Generation with Embedded MATLAB<\/p>\r\n\r\n

File Exchange Submission:<\/strong> Kalman filtering demo in MATLAB with automatic MATLAB-to-C code generation<\/a><\/p>\r\n\r\n

Using Embedded MATLAB, you can generate C-code and test your algorithm on the real hardware with only a few clicks. It significantly reduces the turnaround time of design iterations. <\/p>\r\n\r\n

\"Design<\/p>\r\n\r\n

For the Kalman filter in Houman's submission, the equations are implemented in MATLAB as you would see them in a book:<\/p>\r\n\r\n

\"Kalman<\/p>\r\n\r\n

Then using emlc<\/a>, the algorithm is converted to C code. For example, the last line of the above code is turned into:<\/p>\r\n\r\n

\"Kalman<\/p>\r\n\r\n

So now I recommend that you get yourself a drink, sit down and watch Houman's webinar!<\/p>\r\n\r\n\r\n

Now it's your turn<\/strong><\/p>\r\n\r\n
