Returns a new valarray containing the elements of the array indicated by the argument. The elements in the argument are interpreted as the indices of elements of this valarray to copy to the return valarray.

Parameters
__iThe valarray element index list.
Returns
New valarray containing elements in __s.

◆ operator[]() [7/10]

template<typename _Tp>
_Tp & std::valarray< _Tp >::operator[] ( size_t __i)
inlinenoexcept

Return a reference to the i'th array element.

Parameters

◆ operator[]() [9/10]

template<typename _Tp>
slice_array< _Tp > std::valarray< _Tp >::operator[] ( slice __s)
inline

Return a reference to an array subset.

Returns a new valarray containing the elements of the array indicated by the slice argument. The new valarray has the same size as the input slice.

slice.
Parameters
__sThe source slice.
Returns
New valarray containing elements in __s.

Definition at line 876 of file valarray.

◆ operator[]() [10/10]

template<typename _Tp>
_Expr< _SClos< _ValArray, _Tp >, _Tp > std::valarray< _Tp >::operator[] ( slice __s) const
inline

Return an array subset.

Returns a new valarray containing the elements of the array indicated by the slice argument. The new valarray has the same size as the input slice.

See also
slice.
Parameters
__sThe source slice.
Returns
New valarray containing elements in __s.

Definition at line 868 of file valarray.

◆ resize()

template<class _Tp>
void std::valarray< _Tp >::resize ( size_t __size,
_Tp __c = _Tp() )
inline

Resize array.

Resize this array to size and set all elements to c. All references and iterators are invalidated.

Parameters
__sizeNew array size.
__cNew value for all elements.

Definition at line 1044 of file valarray.

◆ shift()

template<class _Tp>
valarray< _Tp > std::valarray< _Tp >::shift ( int __n) const
inline

Return a shifted array.

A new valarray is constructed as a copy of this array with elements in shifted positions. For an element with index i, the new position is i - n. The new valarray has the same size as the current one. New elements without a value are set to 0. Elements whose new position is outside the bounds of the array are discarded.

Positive arguments shift toward index 0, discarding elements [0, n). Negative arguments discard elements from the top of the array.

Parameters
__nNumber of element positions to shift.
Returns
New valarray with elements in shifted positions.
