I really like the new graph visualization functions that were introduced in R2015b. I particularly like the various options for laying out the graph so you can get a nice picture quickly and easily.... 더 읽어보기 >>

In a recent post, I talked about an interesting edge case in the contour function. Today I'd like to talk about another one. This is how contour handles infinities.Let's start with a simple example.... 더 읽어보기 >>

Today we're going to look at how MATLAB Graphics uses memory. First we need a way to tell how much memory MATLAB is using. Because I'm using a Windows system, I can use the memory function.... 더 읽어보기 >>

In an earlier post, we discussed how the contour functions interpolate between values. Another important issue is how the contour functions deal with contour levels which are exactly the same as values in the input data. Some users are often surprised by what happens in this case because there are some subtle issues involved. Let's take a detailed look.... 더 읽어보기 >>

Fill BetweenOne question I'm often asked is how to fill the area between two plotted curves. It is possible to do this, but it involves some details which aren't obvious, so let's walk through what's... 더 읽어보기 >>

Homogeneous CoordinatesIn my recent posts about tiling polygons (link1, link2), you might have noticed that I used a rather unusual representation for my coordinates.Instead of having a vector of X... 더 읽어보기 >>

What is a Contour?Last year we explored how surfaces perform interpolation. Today we're going to take a look at some closely related functions; the contour family. The family of contour functions... 더 읽어보기 >>

Tiling QuadrilateralsLast time I was talking about the new pentagon tiling which was recently discovered. There are lots of other wonderful things to explore in how polygons tile the plane. One of my... 더 읽어보기 >>

Like most computer graphics programmers, I've always been fascinated by the different types of regular tilings of the plane. There was recently some very big news (NPR, the Guardian) in the tiling... 더 읽어보기 >>

Transparency in 3DTransparency is a very useful feature when creating pictures in 3D. But there are a suprising number of things to think about when you're using transparency in 3D.Let's look at a... 더 읽어보기 >>
