Produces all necessary common memory for LMVM approximations based on the solution and function vectors provided. If <A HREF="../Mat/MatSetSizes.html#MatSetSizes">MatSetSizes</A>() and <A HREF="../Mat/MatSetUp.html#MatSetUp">MatSetUp</A>() have not been called before <A HREF="../KSP/MatLMVMAllocate.html#MatLMVMAllocate">MatLMVMAllocate</A>(), the allocation will read sizes from the provided vectors and update the matrix.
