Detailed Description

template<typename T>
class alps::alea::ndview< T >

Data view as a thin wrapper around a continuous multi-dimensional array.

Basically collects a pointer continuous array in ROW-MAJOR format (vector, transposed Eigen array, C array etc.) together with its shape. Note that the view neither owns the data pointer nor the shape pointer. Thus it amends view<T> with shape information.
