Hi all, In my parallel code, I want to solve the eigenvalues of a small matrix (e.g. 3 by 3) in serial on each processor.
I know Step-36 depends on MPI communication to create the eigenfunctions and to solve the problem, BUT I only need to compute the eigenvalues of a small matrix in serial on each processor. *So, is there a easy way to do this, perferly with matrix type FullMatrix<double>?* Actually I also have a look at the function "EigenInverse <https://www.dealii.org/current/doxygen/deal.II/classEigenInverse.html#a9b2fb99066b64446e66f764a3500050c> (SolverControl <https://www.dealii.org/current/doxygen/deal.II/classSolverControl.html> &cn, VectorMemory <https://www.dealii.org/current/doxygen/deal.II/classVectorMemory.html>< VectorType > &mem, const AdditionalData <https://www.dealii.org/current/doxygen/deal.II/structEigenInverse_1_1AdditionalData.html> &data=AdditionalData <https://www.dealii.org/current/doxygen/deal.II/structEigenInverse_1_1AdditionalData.html>())", which may be a good choice. But I do not understand the description of the second parameter " VectorMemory <https://www.dealii.org/current/doxygen/deal.II/classVectorMemory.html>< VectorType > &mem", and thus I dont know how to use this solve function. *Maybe someone can show me an example of this function.* Many thanks in advance. -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
