Member Function Documentation

doit()

template<class T >

carto::VolumeRef< T > AimsEigen< T >::doit	(	carto::VolumeRef< T >	,
		carto::VolumeRef< T > *	wi = NULL
	)

Eigen system resolution function.

\ The various computation function used within this one are adapted from the Numerical Recipes in C.\ This function returns the diagonal matrix of eigenvalues, and the input matrix is transformed into a matrix which columns are the eigenvectors. \

Parameters

wi	return the diagonal matrix of the imaginary parts of the eigenvalues if *wi exists.

template<class T >

void AimsEigen< T >::sort	(	carto::VolumeRef< T >	eigenvectors,
		carto::VolumeRef< T >	eigenvalues,
		carto::VolumeRef< T > *	wi = NULL
	)

Sort the eigenvectors and eigenvalues in decreasing order.
