class _Array< _Tp >

Detailed Description

template<class _Tp>
class std::valarray< _Tp >

Smart array designed to support numeric processing.

A valarray is an array that provides constraints intended to allow for effective optimization of numeric array processing by reducing the aliasing that can result from pointer representations. It represents a one-dimensional array from which different multidimensional subsets can be accessed and modified.

Parameters:
Tp Type of object in the array.

Member Function Documentation

template<class _Tp>
_Expr< _RefFunClos< _ValArray, _Tp >, _Tp > std::valarray< _Tp >::apply (  _Tp   func(const _Tp &)  )  const [inline]
 

Apply a function to the array.

Returns a new valarray with elements assigned to the result of applying func to the corresponding element of this array. The new array is the same size as this one.

Parameters:
func Function of const Tp& returning Tp to apply.
Returns:
New valarray with transformed elements.

Definition at line 886 of file valarray.

template<class _Tp>
_Expr< _ValFunClos< _ValArray, _Tp >, _Tp > std::valarray< _Tp >::apply (  _Tp   func(_Tp)  )  const [inline]
 

Apply a function to the array.

Returns a new valarray with elements assigned to the result of applying func to the corresponding element of this array. The new array is the same size as this one.

Parameters:
func Function of Tp returning Tp to apply.
Returns:
New valarray with transformed elements.

Definition at line 878 of file valarray.

template<class _Tp>
valarray< _Tp > std::valarray< _Tp >::cshift (  int   )  const [inline]
 

Return a rotated 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) size(). The new valarray is the same size as the current one. Elements that are shifted beyond the array bounds are shifted into the other end of the array. No elements are lost.

Positive arguments shift toward index 0, wrapping around the top. Negative arguments shift towards the top, wrapping around to 0.

Parameters:
n Number of element positions to rotate.
Returns:
New valarray with elements in shifted positions.

valarray<_Tp>& std::valarray< _Tp >::operator|= (  const _Tp &   ) 
 

Set each element e of array to e | t.

template<class _Tp>
_UnaryOp<__bitwise_not>::_Rt std::valarray< _Tp >::operator~ (   )  const
 

Return a new valarray by applying unary ~ to each element.

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

Resize array.

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

Parameters:
size New array size.
c New value for all elements.

template<class _Tp>
valarray< _Tp > std::valarray< _Tp >::shift (  int   )  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 is the same size as the current one. New elements without a value are set to 0. Elements whos 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:
n Number of element positions to shift.
Returns:
New valarray with elements in shifted positions.

template<class _Tp>
size_t std::valarray< _Tp >::size (   )  const [inline]
 

Return the number of elements in array.

template<class _Tp>
_Tp std::valarray< _Tp >::sum (   )  const [inline]
 

Return the sum of all elements in the array.

Accumulates the sum of all elements into a Tp using +=. The order of adding the elements is unspecified.
