static void Dune::DynamicMatrixHelp::eigenValuesNonSym ( const DynamicMatrix< K > &  matrix, DynamicVector< C > &  eigenValues  )

static

calculates the eigenvalues of a symmetric field matrix

Parameters

[in]	matrix	matrix eigenvalues are calculated for
[out]	eigenValues	FieldVector that contains eigenvalues in ascending order

Note

LAPACK::dgeev is used to calculate the eigen values
