class template


template <class T> class valarray;
Valarray class
A valarray object is designed to hold an array of values, and easily perform mathematical operations on them. It also allows special mechanisms to refer to subsets of elements in the arrays (see its operator[] overload).

Most mathematical operations can be applied directly to valarray objects, including arithmetical and comparison operators, affecting all its elements.

The valarray specification allows for libraries to implement it with several efficiency optimizations, such as parallelization of certain operations, memory recycling or support for copy-on-reference / copy-on-write optimizations.

Template parameters

Type of the elements contained in the valarray.
This shall be a value type: i.e., an arithmetic type, a pointer, or a class that behaves like these (such as complex or another level of valarray).
