PCLMVM

A preconditioner constructed from a MATLMVM matrix. If the preconditioner matrix is not of type MATLMVM, an internal matrix is used. Options for the internal MATLMVM matrix can be accessed with the -pc_lmvm_ prefix. Alternatively, the user can pass a suitable matrix with PCLMVMSetMatLMVM().
