Member Function Documentation

template<typename T , unsigned int dim>

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

inline

This function must be called before value.

it calculate the scalar product before return the values

Definition at line 1423 of file Point_operators.hpp.

template<typename T , unsigned int dim>

template<typename orig , typename exp1 , typename exp2 , unsigned int op>

point_expression<T[dim]>& point_expression< T[dim]>::operator= ( const point_expression_op< orig, exp1, exp2, op > &  p_exp )

inline

Operator= for point expression.

Template Parameters

orig	origin type
exp1	expression 1
exp2	expression 2
op	operation

Parameters

point

expression

Returns

a point expression

Definition at line 1408 of file Point_operators.hpp.

template<typename T , unsigned int dim>

T point_expression< 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
