Community Favorite Accelerators 5

Posted by Seth Popinchalk,

In a recent post, I kicked off the discussion of Simulink workflow accelerators. The comments for that post were a great look at ways people work with Simulink. The discussion reminded me of some tricks I had forgotten about, and I learned some new ones. Do you know what you... read more >>

What’s in your model? 6

Posted by Seth Popinchalk,

This morning I was telling my colleague Rob about the blog post I was writing on sample time colors. We talked about models that demonstrated the concept, and he dove into his computer to find an example he had made a couple years ago. I liked the model, so I asked... read more >>

Announcing SimElectronics! 7

Posted by Seth Popinchalk,

In early April, our physical modeling team released a new add-on for Simulink, SimElectronics.
SimElectronics extends Simscapeby adding tools for modeling electronics and electromechanical systems…. read more >>

The Simulink Central Community 4

Posted by Seth Popinchalk,

The MATLAB Central community covers a wide range of MathWorks products. After a quick glance, you might not guess there is a Simulink/Real-Time Workshop/Model-Based Design sub-culture, but there is, and I’m going to tell you I stay connected to it using the Simulink newsgroup.... read more >>

How to draw ODEs in Simulink 26

Posted by Seth Popinchalk,

I remember while learning Simulink, drawing ordinary differential equations was one of the early challenges. Eventually I discovered a few steps that make it easier. First, rewrite the equations as a system of first order derivatives. Second, add integrators to your model, and label their inputs and outputs. Third, connect... read more >>

R2007b+ Now Available: Simulink Bug Fixes 2

Posted by Seth Popinchalk,

Have you ever been in this situation: You run into a software bug, and you verify that the bug has been fixed in the latest version, but you can't install the latest version to get the bug fix. Why not? Because your team has a coordinated upgrade policy. ... read more >>

Bus Signals in the Generated Code 7

Posted by Seth Popinchalk,

Blog reader Paul J. shared with us his mental model of the bus as a structure. While this isn’t true of virtual buses, it is precisely true of nonvirtual buses. In fact, when you generate the code for a nonvirtual bus using Real-Time Workshop, the result is a structure.... read more >>

Nonvirtual Bus Signals 8

Posted by Seth Popinchalk,

Most Simulink users have a good idea of what a bus signal is but I have found people are not as clear about what distinguishes virtual and nonvirtual buses. We have discussed bus signals in recent posts, and we are now ready to answer blog reader Han Geerligs request for “more explanation on... read more >>
