◆ operator()() [1/2]

template<typename data_type >

Returns i^{th} element.

Parameters
iThe 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.
