Detailed Description
template<typename Derived>
class ndarray::ExpressionBase< Derived >
class ndarray::ExpressionBase< Derived >
CRTP base class for all multidimensional expressions.
ExpressionBase is a CRTP base class for both true array objects (subclasses of ArrayBase) and lazy array expressions, which are created by most arithmetic, bitwise, and logical operations on arrays. These lazy expressions have most of the features of a true array to a const data type.
ExpressionBase also provides implementations for a few STL compatibility and convenience member functions.
The documentation for this class was generated from the following file:
