Detailed Description

A Real vector in SpaceDim-dimensional space.

The class RealVect is an implementation of a Real vector in a SpaceDim-dimensional space. RealVect values are accessed using the operator[] function, as for a normal C++ array. In addition, the basic arithmetic operators have been overloaded to implement scaling and translation operations.

Constructor & Destructor Documentation

RealVect::RealVect (    )

Construct a RealVect whose components are zero.

RealVect::RealVect (  D_DECL(Real i, Real j, Real k)    )

Construct a RealVect given the specific values for its coordinates. D_DECL is a macro that sets the constructor to take CH_SPACEDIM arguments.

RealVect::RealVect (  const RealVect &    rhs )

The copy constructor.

RealVect::RealVect (  const IntVect &    iv )  [inline]

Construct a RealVect from an IntVect by coercing each component from int to Real.
