Detailed Description

template<class T>
class CrystVector< T >

Vector library (Blitz++ mimic) for ObjCryst++.

The CrystVector library is not a new array computation library, despite the appearances. ObjCryst++ should used the Blitz++ array library , which yields excellent performance and simple array expressions. Unfortunately, the memory required to compile the library using gcc is far too high to be reasonable when using complex expressions and optimizing code. So until this has changed, The CrystVector and CrystMatrix library have been created, and these emulate (supposedly exactly) the Blitz++ interface (but not the smart handling of mathematical expressions, so pointers must be used). For documentation about these two libraries you should read the Blitz++ documentation. CrystVector and CrystMatrix use the same kind of storage in memory.

You can use CrystVector_REAL, CrystVector_long,etc... to declare 1D vectors. Macros ensure (well, should) ensure compatibility with Blitz++. (as of april 2001 support of blitz++ is broken).

Todo:
check again Blitz++ support in newer gcc versions.

Member Function Documentation

template<class T >
void CrystVector< T >::reference ( CrystVector< T > &  old,
const long  imin = 0,
const long  imax = 0 
)

Define this vector as a reference to another vector, or part of another vector.

Parameters
oldthe vector this one should point to
imin,imaximax>imin, this vector will point to a part of the other vector, from old(i) to old(imax-1)
