Last week, I posed a Puzzler. I solved it the hard way, because I did not know any of the fancy math that the people in the comments section mentioned. I will leave the closed form solution to them… read more >>
Being a company full of geeks, a fair amount of brainteasers get passed around. One that recently came around got my attention. I knew there was probably math that governed it elegantly, but I did… read more >>
I am pleased to announce that there is a new MATLAB programming contest, and it started a few hours ago. This one is very different from prior contests, it is a free-form visualization contest. It is… read more >>
Often when I post code, there is a discussion of how to optimize it. I tend to subscribe to this maxim:
Rules of Optimization:
Rule 1: Don’t do it.
Rule 2 (for experts only): Don’t do… read more >>
MATLAB challenges get thrown around the halls of The MathWorks with fair regularity. I thought this most recent one would make a good puzzler.
You have a matrix that has 3xN rows and you want to… read more >>
Well, it was a great contest this season. I was very happy to see that each King of the Hill tended to get arguably better than the prior. I wanted to find out how much better, so I used the actual… read more >>
I have been waiting until the daylight portion of the ArmyAnts contest to post this commentary. Jan has done an excellent job with his algorithm. He made only one entry in that time period, and he… read more >>
I love the MATLAB contest, I am not sure if it is more fun to play the contest or to help design and administer it. Either way, I am looking forward to seeing a lot of really great algorithms from… read more >>
This recent puzzler was very successful with entries from four different continents. I can understand the busy researchers of Antarctica not joining in, but I expected to hear from Australia and… read more >>
I get lots of e-mail from blog readers that say they learn a lot from the videos here. Well, this week we want to learn from you.
The Usability team at The MathWorks studies how people actually use… read more >>
