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

[Ivo Maljevic]

If you need to find a quick result than the easiest way is to go through
wolfram alpha. Just enter:
eig{{ a,     b,   a*b  ]},{a+b,  0,    0    } ,{c,     a,     c+b}}

or use the following link:

http://www06.wolframalpha.com/input/?i=eig{{+a%2C+++++b%2C+++a*b++]}%2C{a%2Bb%2C++0%2C++++0++++}+%2C{c%2C+++++a%2C+++++c%2Bb}}

(put the line together if broken).
