internal::HessenbergDecompositionMatrixHReturnType< MatrixType > Struct Template Reference
[Eigenvalues module]


Detailed Description

template<typename MatrixType>
struct internal::HessenbergDecompositionMatrixHReturnType< MatrixType >

Expression type for return value of HessenbergDecomposition::matrixH()

Template Parameters:
MatrixTypetype of matrix in the Hessenberg decomposition

Objects of this type represent the Hessenberg matrix in the Hessenberg decomposition of some matrix. The object holds a reference to the HessenbergDecomposition class until the it is assigned or evaluated for some other reason (the reference should remain valid during the life time of this object). This class is the return type of HessenbergDecomposition::matrixH(); there is probably no other use for this class.
