std::valarray::valarray - std::valarray::valarray

Synopsis

valarray(); (1)
explicit valarray( std::size_t count ); (2)
valarray( const T& val, std::size_t count ); (3)
valarray( const T* vals, std::size_t count ); (4)
valarray( const valarray& other ); (5)
valarray( valarray&& other ) noexcept; (6) (since C++11)
valarray( const std::slice_array<T>& sa ); (7)
valarray( const std::gslice_array<T>& gsa ); (8)
valarray( const std::mask_array<T>& ma ); (9)
valarray( const std::indirect_array<T>& ia ); (10)
valarray( std::initializer_list<T> il ); (11) (since C++11)

Constructs new numeric array from various sources.

1) Default constructor. Constructs an empty numeric array.
2) Constructs a numeric array with count copies of value-initialized elements.
3) Constructs a numeric array with count copies of val.
4) Constructs a numeric array with copies of count values from an array pointed to
by vals. If this array contains less than count values, the behavior is undefined.
5) Copy constructor. Constructs the numeric array with the copy of the contents of
other.
6) Move constructor. Constructs the container with the contents of other using move
semantics.
7-10) Converting constructor. Convert the corresponding data structure to a
valarray.
11) Constructs the numeric array with the contents of the initializer list il.

Parameters

count - the number of elements to construct
val - the value to initialize the elements with
vals - pointer to a C array to use as source to initialize the contents
other - another numeric array to use as source to initialize the contents
sa - slice array to initialize the elements with
gsa - generic slice array to initialize the elements with
ma - mask array to initialize the elements with
ia - indirect array to initialize the elements with
il - initializer list to initialize the elements with

Exceptions

1-5, 7-11) May throw implementation-defined exceptions.
