We discussed a simple 2 by 2 matrix example. Here are some Matlab files and Maple files that support the discussion in class.
Matlab files Driver (Matlab interactive commands)
Subroutine file "detam1.m"
Graph of det(A)-1 for n in 1.e7 to 1.e8 (encapsulated PostScript file)
HTML view of the Maple worksheet (note that this file was generated from within Maple by the "export to HTML" feature, which is remarkably good)
The generating Maple worksheet itself
