Software to find eigenvalues

Question

Is there a software (or website) that is free which can find eigenvalues but with arbitrary constants, say $a,b>0$ being involved?

This example will get you started. It contains eigenvalues further down in the output — Gregor de Cillia, Feb 02 '16 at 19:07

Use wolframalpha for that. The following input gives eigenvalues depending on parameters $a,b$:

eigenvalues {{4,a},{b,-1}}

Here a link.
