The various problems we are having with Pynac vs. Maxima treatment of 'I' are probably related to what you have. I seem to recall some tickets about symbolic matrix operations as well, but that could be unrelated. I know this doesn't help you, but it might help someone else help you :) - kcrisma

I built Sage 4.2.1 on an old (500 MHz) Sun Netra T1. I created the notebook, then tried to 'publish' it. But the URL is incorrect. True this is a local IP, so it will never be routable over the internet (something perhaps Sage should warn), but it is totally wrong. With a URL of http://192.168.

Hi A lecturer returned a year after we posted some messagses, resulting in some bugs identified, some fixed and some still open. The Quantum Spin Chain course repeated now on sage 4.2.1, still computing eigenmatrix'es and involving complex numbers. We try to isolate the problems clearly here:
