C++ Interface to PETSc

petsc-cpp

C++ Interface to PETSc and SLEPc. Currently requires PETSc and SLEPc from master: bitbucket.org/petsc/petsc and bitbucket.or/slepc/slepc

Currently limited to only a few different classes:

PetscContext:

PetscContext is the initialization of Petsc. Create the petsc::PetscContext object at the beginning of main and it will call PetscInit and PetscFinalize for you. Currently doesn't do much more than that.

Vector:

A wrapper for a Petsc Vec object. Has a couple of different member functions, and lacks a default constructor (we don't want one, cause really, you shouldn't be creating a vector this way, using this interface).

Matrix:

A wrapper for a Petsc Mat object. a few member functions, including a get_vectors() method that returns an array of Vectors for your pleasure.

EigenvalueSolver:

A wrapper for a Slepc EPS object. The initializer creates and solves an eigenvalue problem. Currently only works for non-generalized eigenvalue problems.
