Solve generalized eigenvalue problem or reduce it to single

Postby horacioemilio » Thu Mar 22, 2012 4:14 am

We want to accelerate on GPUs the generalized symmetric eigenvalue problem, i.e., Ax=lambda*Bx, where A and B are real matrices. We wonder whether CULA has support for this problem, or if using other CULA functions, we could reduce this problem to the simple eigenvalue problem, A'x=lambda*x

We have plans to add generalized eigen-solvers in the next CULA Dense release.

Are you interested in general or symmetric systems?

only in symmetric systems

from the other side, would it be possible, using CULA tools, to reduce the generalized problem to the single one? (Ax=lambda*x)
