Dear All, I'd like to solve the problem of Generalized EVP where A is positive definite and where B has products only on its diagonal and some of them might be zeros.
I started implementation with modifying the existing example(namely example 2 in the official Slepc site). Instead of using the Matrix viewer object I used? reading A and B matrices directly from text file. Program produces the following? error message, this has been triggered right after?ierr = EPSSolve(eps);CHKERRQ(ierr); call. I supply with main program body and required matrices stored in files. [0]PETSC ERROR: --------------------- Error Message ---------------------------- -------- [0]PETSC ERROR: Object is in wrong state! [0]PETSC ERROR: Not for unassembled matrix! [0]PETSC ERROR: ---------------------------------------------------------------- -------- [0]PETSC ERROR: Petsc Release Version 3.3.0, Patch 6, Mon Feb 11 12:26:34 CST 20 13 I appreciated your help, any other example of solving GEVP with subspace, arnoldi? or Lanczos methods is also wellcome.
