Detailed Description

This module relates to the loading, generation, and check of spectrum provided by the users. This spectrum will be fed into SMG2S for generating a non-Symmetric/Hermitian sparse matrix with it.

Function Documentation

checkNonSymmSpec()

template<typename T , typename S >

S checkNonSymmSpec

(

parVector< std::complex< Base< T >>, S >

spec

)

Check if provided spectrum with conjugate eigenvalues is valid.

Parameters

[in]

spec

the provided spectrum stored in a parVector object with complex scalar.

• Attention, this function is only useful for generating non-Symmetric matrix with conjuagte eigenvalues.

specNonHerm()

template<typename T , typename S >

parVector<T, S> specNonHerm	(	parVectorMap< S >	index_map,
		std::string	spectrum
	)

load user-provided spectrum from local text file for generating non-Hermitian matrix

Parameters

[in]	index_map	the distribution scheme used for building the parVector object which stores the loaded spectrum
[in]	spectrum	path and file name which stores the given eigenvalues.

• Attention, this function is only useful for generating non-Hermitian matrix with conjuagte eigenvalues.

specNonSymm()

template<typename T , typename S >

parVector<T, S> specNonSymm	(	parVectorMap< S >	index_map,
		std::string	spectrum
	)

load user-provided spectrum (only eigenvalues in real) from local text file for generating non-Symmetric matrix

Parameters

[in]	index_map	the distribution scheme used for building the parVector object which stores the loaded spectrum
[in]	spectrum	path and file name which stores the given eigenvalues.

• Attention, this function is only useful for generating non-Symmetric matrix with eigenvalues in real.

specNonSymmCplex()

template<typename T , typename S >

parVector<std::complex<Base<T> >, S> specNonSymmCplex	(	parVectorMap< S >	index_map,
		std::string	spectrum
	)

load user-provided spectrum (conjugate eigenvalues) from local text file for generating non-Symmetric matrix

Parameters

[in]	index_map	the distribution scheme used for building the parVector object which stores the loaded spectrum
[in]	spectrum	path and file name which stores the given eigenvalues.

• Attention, this function is only useful for generating non-Symmetric matrix with conjugate eigenvalues.
