boost::call_traits<DataType>::reference Nektar::NekPoint< data_type >::operator() ( unsigned int  i )

inline

Returns i^{th} element.

Parameters

i	The element to return.

Precondition

i < dim

Returns

A reference to the i^{th} element.

Retrieves the i^{th} element. Since it returns a reference you may assign a new value (i.e., p(2) = 3.2;)

This operator performs range checking.
