Constructor & Destructor Documentation

point_expression()

template<typename T , unsigned int dim>

__device__ __host__ point_expression< const T[dim]>::point_expression ( const T(&)  d[dim] )

inline

construct from an array of dimension dim

Parameters

d

array

Definition at line 1982 of file Point_operators.hpp.

Member Function Documentation

init()

template<typename T , unsigned int dim>

__device__ __host__ void point_expression< const T[dim]>::init ( ) const

inline

This function must be called before value.

it calculate the scalar product before return the values

Definition at line 1992 of file Point_operators.hpp.

value()

template<typename T , unsigned int dim>

__device__ __host__ T point_expression< const T[dim]>::value ( const size_t  k ) const

inline

Evaluate the expression at coordinate k.

It just return the value set in the constructor

Parameters

k	coordinate

Returns

the value
