[SciPy-user] any symbolic manipulation of eigenvalue in Scipy?

[Xiaojian Wang]

Hi,
I would like to know if there is any module in Scipy (or Numpy?),  which has
capability
of symbolic manipulation and can generate matrix's eigenvalues/eigenvectors.

My matrix is symbolic, such as a 3x3 matrix:

[ a,     b,   a*b  ]
[a+b,  0,    0    ]
[c,     a,     c+b]

a,b,c could be any values in my future applications.
if not, do you guy know any other programs can do this?

Many thanks for your help in advance!

Xiaoijan
