Hi,

I want to use dolfin for solving eigenvalue problems. I've installed 
dolfin 0.7.1 with petsc and slepc. The matrix, for which the eigenvalues 
should be computed, is defined in the following way:

PETScMatrix C(TS, TS);
C.set(.....);
C.set(.....);

Now, when I'm trying to solve the problem with:

SLEPcEigenvalueSolver esolver;
esolver.solve(C);

I get the following error message:

What does it meen? And what have I made wrong?
