PCLMVM

A preconditioner constructed from a MATLMVM matrix. If the matrix used to construct the preconditioner 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().
