In the last six months, this blog has taken a sharp turn towards being a video tutorial blog. There are other blogs that have been doing this for a while too. I recently got word about a great… 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 >>

In a recent post, I mentioned LazyWeb It worked better than I expected. Matt posted some code that I requested that will highlight a line when you click on it. This works exactly as hoped. Thanks… 続きを読む >>

In a recent post, I showed how Roger did a mash-up of two prior Picks. In the video, I actually made a request that someone make some further modifications to the code. This concept of asking other… 続きを読む >>

I love the MATLAB contest, one of the great things about working at The MathWorks is I get to ‘play test’ the contest before it goes live. One of the bad things about working at The… 続きを読む >>

Two minute video shows how to fit a surface to nonuniform data.
Real data is not always on a nice X,Y grid, but the MATLAB commands
SURF and MESH expect them to be. GRIDDATA and MESHGRID help to fix… 続きを読む >>

Two minute video shows how to validate GUI input. This makes sure that user input will not break your code. This example makes sure that the edit box value is not greater than twelve. This technique… 続きを読む >>

When I look at code written by new users, sometimes, I will see code like this:
a = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15];
There is an easier way:
a = 1:13;
