I have tried to do it non-symbolically, but I think it is rather inelegant. I am also trying to promote the use of python/sage over the use of Mathematica with my fellow students and it is somewhat important to show that they can do the same thing for free with other advantages. Since Mathematica is able to calculate the eigenvalues without any problem or delay, it is hard to convince someone to switch to a system that takes so much longer and is not as reliable.
I just installed the python3 version of sympy, which didn't it done either... You can by the way eliminate the recursion depth error by adding sys.setrecursionlimit(2**20) to your file. So far, this is what I found out from testing with various systems: Sage with python 2.6: calculates up to 36x36 in a reasonable time (65s) python 2.7/python 3.2: calculate up to ~ 20x20 Sage with Maxima for calculation works faster, but I have problem with really big matrices like 400x400 ... working on it though! -- You received this message because you are subscribed to the Google Groups "sympy" group.
