I suppose this makes sense; thanks for the info.
Two questions: 1) Has anyone had success with eigs on a Mac? Perhaps, via direct compilation of Octave as described here: http://wiki.octave.org/wiki.pl?OctaveForMac
2) My impression is that eigs is unlikely to every be included in the standard Octave distribution due to license concerns involving ARPACK. Is this correct?
I ask the second question more for my students than for myself. I'll be teaching a class in numerical linear algebra next semester. Our students have some access to Matlab on campus, but I'd like to let them know about Octave as a viable alternative to potentially save some of them some money and to expose them to open source software. Many of our applications of interest involve eigensystems of large sparse matrices, however, so a working eigs function is really essential.
