As you may know, it is easy to run Simulink models on a set of supported target hardware. This has been possible since R2012a. Even if we add more targets and support more features for each target... read more >>

If you are going to work with C or C++ S-Functions, you will probably need to do some debugging. My advice is: Don't go with the printf debugging approach. I did that for too long and now I... read more >>

In a previous post, I showed an example of a MATLAB S-Function with a discrete state This week, we continue in the same direction and implement an S-Function with a continuous state. Continuous... read more >>

A few weeks ago, I noticed the following question on MATLAB Answers by K E: What are continuous and discrete states in Simulink? In my opinion, the best way to understand how states work in... read more >>

I have to admit... before joining MathWorks, I was afraid of S-Functions. Now this makes me laugh, because I know that writing an S-Function is very powerful and not that complicated. In my... read more >>

Today I will describe how to use a variable sample time s-function to schedule events in the future. This topic is fairly advanced, so hold on tight... or as we say where I come from: Attachez vos... read more >>

I received requests recently about variable-size signals and the Unit Delay block. One question, many answers What should a Unit Delay do when the size of a signal changes? Unfortunately,... read more >>

As you may know, Space Shuttle Atlantis is about to return this weekend from man’s last visit to the Hubble Telescope.  Those astronauts took some major risks to repair our favorite and most famous... read more >>

This almost never happens, but today I get to share with you an undocumented Simulink capability! In R2009a the S-function builder has the ability to accept bus signals at its input and output... read more >>
