PCSVD
Use pseudo inverse defined by SVD of operator
Options Database
-pc_svd_zero_sing <rtol> Singular values smaller than this are treated as zero -+ -pc_svd_monitor Print information on the extreme singular values of the operator
Developer Note: This implementation automatically creates a redundant copy of the
matrix on each process and uses a sequential SVD solve. Why does it do this instead
of using the composable PCREDUNDANT object?
