# Mathematica: Eigenvalues for a large symbolic matrix

1. Jul 13, 2010

I'm trying to compute the eigenvalues for a 32x32 symbolic matrix (with one variable) in Mathematica. I get the following error:

Eigenvalues::eival: Unable to find all roots of the characteristic \
polynomial. >>

What could be a possible way to proceed?

Thanks,
Schez

Have you tried both Eigenvalues[ ] and Eigensystem[ ]? From which function did you get this error? If it's in one variable then I don't really see why Eigensystem wouldn't work.

Try to assume ranges for the constants, i.e. greater than 0, less than 0, etc...
