In this short video, I explore the math behind this joke: An infinite number of mathematicians walk into a bar. The 1st orders a 1 beer. The 2nd orders 1/2 a beer. The 3rd orders … 続きを読む >>
I love getting well formed question and challenges from fellow MATLAB users. This week I got one that works very well as a video. The problem was trying to index into a vector with a vector of… 続きを読む >>
I think it is best to do these tutorials based on solving realistic coding challenges. In helping to write the code for the next MATLAB contest, I had a situation where I wanted two images to be… 続きを読む >>
A question that comes across my inbox from time to time is how to save the state of a GUI between session. There are few methods for doing this, one is using the HGSAVE command to save the .FIG file… 続きを読む >>

In the recent Puzzler about the spiral, most of the code that was produced went along the following: Create the spiral matrix Find the indices of the ‘1’s in the binary targets… 続きを読む >>
I recently got an e-mail from a MATLAB user that had a large dataset in Excel. They wanted to import the data and “take the average of the graph”. It turns out that meant fitting a… 続きを読む >>
I am about to leave for a recruiting trip to Carnegie Mellon University. Be sure to stop by the booth and say hello (or ARGHHH! if I see you on Friday, International Talk like a Pirate Day!) If you… 続きを読む >>
Today, Brett, Bob and Jiro have completed their inheritance of Pick of the Week blog. There is a fine heritage of Applications Engineers running the Pick of the Week blog. Scott Hirsch and I… 続きを読む >>
Very often MATLAB users want to be able to process a set of files from a directory. In this video, I show how you can look through a directory seeking files of the form “data###.dat” and… 続きを読む >>
