getEigenvalue()

template<typename Scalar >

Scalar syten::getEigenvalue ( DenseTensor< 2, Scalar > const &  o, DenseTensor< 1, Scalar > const &  v  )

inline

Returns the eigenvalue of the specified eigenvector relative to the specified matrix.

Parameters

o	matrix of which v is an eigenvector
v	eigenvector of the matrix o

Returns

the eigenvalue \( λ \) s.t. \( o v = λ v \)

If debugging is enabled, a check is made to ensure that v is indeed an eigenvector of o, otherwise, the first nonzero element of v is compared to the corresponding element of o v and the ratio is returned.
