Add MatrixShell support to PETSc solver classes #53

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
The MatrixShell is not supported by the PETSc solvers. We need to make the link 
with the PETSc MATSHELL
data structure.

MatrixShell is a very important tool for solving linear systems using Krylov 
solvers(e.g. CG, GMRES). One of its specificity is that we have not necessarily 
need to know the matrix entries, but just only its action on a vector(e.g. 
matrix-vector multiply).
