permute()

template<typename Scalar >

DenseTensor<2, Scalar> syten::Delinearise::permute ( std::vector< DenseTensor< 1, Scalar > > &  columns, std::vector< DenseTensor< 1, Scalar > > &  thresh  )

inline

Permutes columns in columns and thresh such that the columns with maximal zeroness score are in the front.

Returns a permutation matrix to be multiplied from the right into the permuted matrix to restore the original matrix.
