Index syten::rank | ( | DenseTensor< 2, double > const & | a | ) |
Estimates the rank of a real matrix A using QR with pivoting.
Does not perform row sorting or column scaling. For optimal stability, you should do both, using scale_columns_2norm
and sort_rows_infnorm
.
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
