Yesterday I came across this model: At first look, one might think that these two implementations should give the same results. However this is not the case because the delayed data is... 続きを読む >>

Among all the posts I made in the last year, one that received many comments is How to customize the Simulink Scope. In this post, I suggested to use the simplot function to customize the way you... 続きを読む >>

MATLAB R2011b is available for download since midnight September 1, 2011! Each new release brings some excitement, but for me this one is especially exciting. I have been waiting for a long time... 続きを読む >>

Today I want to share a useful trick to control signal logging using the Model Explorer. Enabling Logging from the Signal Properties dialog Until recently, to enable logging of signals I was... 続きを読む >>

Did you notice the new Dataset logging format available in R2011a? This new format offers a lot of advantages over the old ModelDataLogs format. Here are a few examples. Timeseries... 続きを読む >>

Wouldn't it be great if you could analyze a Simulink model and certify that it will never encounter design errors like divisions by zero and overflows? Since MATLAB R2011a, this is possible! This... 続きを読む >>

Working in technical support, I receive a lot of models. Sometimes I am impressed by very clever implementations, but sometimes the only thing coming to my mind is "Why is he doing that?". Here are a... 続きを読む >>

Today guest blogger Arnaud Miege presents a great example of adopting Model-Based Design. As an application engineer, I meet lots of customers applying MathWorks tools in many different... 続きを読む >>

Today, we had a short conversation at the start of a meeting. It went something like this: Guy: Yesterday I opened the main page of the MathWorks website and saw a link to a new video about... 続きを読む >>

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,... 続きを読む >>
