Detailed Description

Implementation of the DMRGBlockContainer class which is the core container class for DMRG objects and operations.

Classes
struct	Eigen_t
	Storage for information on resulting eigenpairs of the reduced density matrices. More...

struct	Op
	Defines a single operator to be used for performing measurements. More...

class	DMRGBlockContainer< Block, Hamiltonian >
	Contains and manipulates the system and environment blocks used in a single DMRG run. More...

Functions
PETSC_EXTERN PetscErrorCode	Makedir (const std::string &dir_name)
	Creates a directory named `dir_name`. More...

bool	greater_eigval (const Eigen_t &e1, const Eigen_t &e2)
	Comparison operator for sorting Eigen_t objects by decreasing eigenvalues. More...

bool	less_blkIdx (const Eigen_t &e1, const Eigen_t &e2)
	Comparison operator for sorting Eigen_t objects by increasing blkIdx (decreasing qn's) More...

Macros
#define	CheckInitialization(init, mpi_comm)
	Returns an error if DMRGBlockContainer object is not initialized. More...

#define	PrintLines()
	Print out horizontal lines of `-` characters. More...

#define	PRINTLINES()
	Print out horizontal lines of `=` characters. More...

#define	PrintBlocks(LEFT, RIGHT)
	Printout the number of sites in each of the input blocks. More...

#define	ASSIGN_VAR(MAP, VAR)
	Assign a value into key-variable and throw a proper PETSc error when lookup fails. More...

#define	PRINT_VAR(VAR) std::cout << " " << std::setw(20) << #VAR << " = " << VAR << std::endl;
	Print the value of a given variable name. More...

#define	OpIdxToStr(OPTYPE, IDX) (OpToStr(OPTYPE)+std::to_string(IDX))
	Convert the input operator type and index to string. More...

#define	GetOpMats(OPMATS, CORRSIDEOPS, OPID) (OPMATS.at(OpIdxToStr(CORRSIDEOPS.at(OPID).OpType,CORRSIDEOPS.at(OPID).idx)))
	Get the operator matrix corresponding to the given type, size and index. More...

#define	MAX_SWEEP_IDX 10000
	Hardcoded maximum number of sweeps to be searched. More...
