I have a generalised eigenvalue problem of the form(adsbygoogle = window.adsbygoogle || []).push({});

[tex]A\boldsymbol{u} = \lambda B\boldsymbol{u}\;,[/tex]

where A and B are symmetric matrices with real symbolic entries. I'm trying to compute the eigenvalues with Mathematica using the command

which according to the documentation should work. However, when I do, Mathematica returns the following errorCode (Text):Eigenvalues[{A,B}]

The documentation is of no help. Does anyone have any suggestions?Code (Text):Eigenvalues::exnum: Eigenvalues has received a matrix with non-numerical or exact elements.
