Caveat: I ran this using Mono, so I'm not sure if it's really a problem
with Mono, or a bug in IronPython. It looks like there are some
problems with arrays, but someone with a Win32 version should check
this.
The following uses Mapack, downloadable from Lutz Roeder's site.
Intended usage from C# would be:
Matrix A = new Matrix(3, 3);
A[0,0] = 2.0; A[0,1] = 1.0; A[0,2] = 2.0;
A[1,0] = 1.0; A[1,1] = 4.0; A[1,2] = 0.0;
A[2,0] = 2.0; A[2,1] = 0.0; A[2,2] = 8.0;
