# 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()`.
