The dodecahedron is a particularly interesting polyhedron. It's full of interesting five-fold symmetries. Let's take a look at a couple of them.First we'll need the vertices. There's an interesting... read more >>

Another new feature that I really like in R2016a is the upgraded fplot function and all of the new members of the fplot family.The fplot function has been around for a long time. The basic idea is... read more >>

One of the features I love in R2016a is the new yyaxis function. This is a new way to create plots which have two independent Y's, like the older plotyy function. Let's take a look at how yyaxis... read more >>

As the Wind BlowsNOAA maintains a number of buoys that collect weather data, and they publish the data from them on their website.There are four of these buoys just outside Boston harbor. They are... read more >>

Recently I heard from a MATLAB user who was trying to draw tubes along a curve using this blog post I wrote a while back. Unfortunately her curve was a bit more complex than the ones I used in that... read more >>

One type of question that I'm often asked is about how to use various visualization techniques with what is sometimes called "scatter data". This is data that is a list of individual measurements.... read more >>

Last time, when I was talking about permutohedra, we saw how truncated octahedra fill 3D space with no gaps. There are a number of shapes with this property, and they have the lovely old family name... read more >>

In earlier posts we've looked at tiling quadrilaterals and pentagons. So what about hexagons? I'm sure you've seen tilings of regular hexagons. They're popular in floor tiles and game tiles. Even... read more >>

I recently answered a question on MATLAB Answers about how patch interpolates color data. This is a question I get a lot because it's a bit more complicated than you might expect. Let's take a close... read more >>
