rank() [4/4]

Index syten::rank

(

DenseTensor< 2, std::complex< double > > const &

a

)

Estimates the rank of a complex 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.
