Texas A&M University professor Tim Davis uses sparse matrix algorithms to create works of electronic art by visualizing music.
Davis notes many researchers and artists have tried to go in the reverse direction and use mathematical rules to generate music.
His algorithms are a form of music visualization in which an entire piece of music is rendered in a single image.
Yahoo researcher Yifan Hu used Davis' matrices to test his visualization algorithms, and both researchers have worked on the graphviz algorithm, which turns a mathematical description of a graph into a visualization of nodes and edges.
Davis' research has resulted in the creation of new algorithms as well as new software. To convert the algorithms into usable tools, massive amounts of code need to be generated perfectly, without any bugs.
"My tool is not a paintbrush, it's an algorithm and Matlab--it's math," Davis says.
