Back in February 2009 I posted about how to test for NaN in Simulink.  The approach I talked about was more of a logical experiment based on the special properties of NaN than an... 続きを読む >>

Last week the MathWorks released the R2009b family of
products.  There are many new capabilities in the latest release and with this
blog post, I want to highlight a some of the features in Simulink... 続きを読む >>

Did you ever notice that a BEEP in Simulink means something different from a BEEP in MATLAB? BEEP, What BEEP?  What I’m talking about is that bell character you sometimes hear.  In older... 続きを読む >>

In a previous post, I answered a question about how to model an If-Else behavior.  Here I will restate the algorithm I want to create: if(sel==0) out = 2*in1; elseif (sel==1) out =... 続きを読む >>

My colleague Sam and I wanted to find an example model with about 10,000 blocks.  I suggested the HL-20 model from the Aerospace Blockset, asbhl20.mdl.  Sam decided to measure the total number of... 続きを読む >>

Earlier this week, Guy and I were discussing the sometimes-strange behavior of mux and bus signals.  Sometimes people find a Mux block in their model that appears to output a bus signal.  In this... 続きを読む >>

Today I am pleased to share a post from regular guest blogger, Guy Rouleau.  Enjoy! I often use Simulink to model the dynamics of simple systems. In most cases, the Simulink default... 続きを読む >>

When you are new to something, it always helps to get a mental picture of how that something works.  Since I learned Simulink over 10 years ago, I have developed my own mental model of Simulink... 続きを読む >>

Many people talk about the anticipation of the next iPhone, Kindle or some must-have techno gadget. I am looking forward to the next release of MATLAB. I downloaded the prerelease last week and now... 続きを読む >>

Balaji Kalluri asked a question in the comments of a post about the MUX block.  Balaji asked: Hi All I would be highly obliged, if someone can show me a route to model a typical ... 続きを読む >>
