Hi all,
I am quite new to sympy.
When I type the following
a = symbols('a')
m = Matrix( [ [a, 0], [0, 1] ] )
m.eigenvals()
I expect the answer to
{a: 1, 1: 1}
But I get
{a/2 + sqrt((a - 1)**2)/2 + 1/2: 1, a/2 - sqrt((a - 1)**2)/2 + 1/2: 1}
I think first the characteristic polynomial is computed and then roots are
found. This produces the mess. Wouldn't it be better to try to factor the
characteristic polynomial first and then find roots?
