From Wikipedia, the free encyclopedia

Above are some of the pictures I contributed to Wikipedia. All the pictures have the source code included (click on the picture). The exception is the finite element triangulation picture, whose code I lost. The codes are in MATLAB or Xfig, and I place them in the public domain.

All codes are rather carefully written, and some have detailed comments. It is hoped that they may teach one a thing or two about graphing things in MATLAB.

Most pictures were generated as eps files, and were converted to png with the ImageMagick's convert tool, which is available on Unix. That command can be called for example as

convert -antialias -density 400 -scale 25% picture_in.eps picture_out.png

where the density option specifies how high the resolution should be, and the scale parameter shrinks the picture by given amount.
