_______________________________________________________
Details:
When going through the examples contained in this document:
http://www.cs.yale.edu/homes/spielman/561/lect01-15.pdf and in particular
towards the end with the dodecahedron example, the output from Octave differs
significantly from that of Matlab. In particular, the "sa" option for eigs()
forces an ordering on the ouput eigenvalues/vectors which doesn't seem to be
observed. When following through the example, the output is signficantly
different.
I conferred with others on the IRC channel, and they confirmed that the bug is
also in 4.0.
