Notice the link at the bottom for a one minute survey that can get you into a drawing for a MATLAB t-shirt!
This ten minute video shows how to modify the help example for INPOLYGON to generate a set… 続きを読む >>

Thank you to everyone that answered the survey from my last post. I will be processing the results and reporting in my next post.
Changes are already being planned based on the results.

In an earlier post, I covered how to collect data from a data acquisition board. This post will do something similar for an oscilloscope. This time instead of using the Data Acquisition Toolbox we… 続きを読む >>

Most MATLAB functions are overloaded. That means that there are several ways to call them and that MATLAB will “Do The Right Thing” based on the number and types of inputs. As a simple… 続きを読む >>

This three minute video takes a look at the “Switch case” flow control statement and contrasts it with the more familiar “If elseif” flow control statement.
Often times,… 続きを読む >>

This is the next in a series of advanced topics in MATLAB. My definition of “Advanced” is somewhat nebulous and arbitrary, so even newer users can give this a watch.
Two and a half… 続きを読む >>

This six and a half minute video shows a function being created in MATLAB, then it shows a subfunction being added. Functions are a way of adding to the MATLAB language. This video shows the… 続きを読む >>

I was working with a MATLAB user that had a large number of data points in the form of x,y,z triples. He was mostly interested in the density of these data points over the range of the data. At… 続きを読む >>

This six minute video shows you how to use the debugger and other tools to step through complicated code and understand what is really going on. By taking a complicated expression and breaking it… 続きを読む >>

First, be sure to check out the new home of LazyWeb. We had three of the challenges closed, but there are three still open. We are sending out MATLAB prize packages to all that solved a challenge,… 続きを読む >>
