Detailed Description

template<class real>
class Eagle::STA::CartesianChart4D< real >::vector

4-dimensional vector.

Constructor & Destructor Documentation

vector() [1/2]

template<class real>

Eagle::STA::CartesianChart4D< real >::vector::vector ( const Base_t & V )

inline

Constructor from base class.

Note that this constructor is implicit, whereas the base class constructor is explicit.

Referenced by dot, inv(), norm, norm2, operator()(), operator*(), operator*, operator-, operator/, vector(), vector(), vector(), and vector().

vector() [2/2]

template<class real>

Eagle::STA::CartesianChart4D< real >::vector::vector ( )

inline

Evil default constructor.

Not sure if it should do anything or nothing. Primary purpose is for use within arrays. The user shouldn't expect uninitialized variables to contain anything useful.
