Array — 1-D array used in linear algebra.  


#include <ql/math/array.hpp>

Public Types

typedef Size size_type
typedef Real value_type
typedef Real * iterator
typedef const Real * const_iterator
typedef boost::reverse_iterator< iterator > reverse_iterator
typedef boost::reverse_iterator< const_iterator > const_reverse_iterator

Public Member Functions

Constructors, destructor, and assignment

Array (Size size=0)
creates the array with the given dimension
Array (Size size, Real value)
creates the array and fills it with value
Array (Size size, Real value, Real increment)
creates the array and fills it according to $ a_{0} = value, a_{i}=a_{i-1}+increment $
Array (const Array &)
Array (const Disposable< Array > &)
template<class ForwardIterator > Array (ForwardIterator begin, ForwardIterator end)
creates the array from an iterable sequence
Array & operator= (const Array &)
Array & operator= (const Disposable< Array > &)
bool operator== (const Array &) const
bool operator!= (const Array &) const

Vector algebra
v += x and similar operation involving a scalar value are shortcuts for $ rall i : v_i = v_i + x $

v *= w and similar operation involving two vectors are shortcuts for $ rall i : v_i = v_i imes w_i $


all arrays involved in an algebraic expression must have the same size.

const Array & operator+= (const Array &)
const Array & operator+= (Real)
const Array & operator-= (const Array &)
const Array & operator-= (Real)
const Array & operator*= (const Array &)
const Array & operator*= (Real)
const Array & operator/= (const Array &)
const Array & operator/= (Real)

Element access

Real operator[] (Size) const
Real at (Size) const
Real front () const
Real back () const
Real & operator[] (Size)
Real & at (Size)
Real & front ()
Real & back ()


Size size () const
dimension of the array
bool empty () const
whether the array is empty

Iterator access

const_iterator begin () const
iterator begin ()
const_iterator end () const
iterator end ()
const_reverse_iterator rbegin () const
reverse_iterator rbegin ()
const_reverse_iterator rend () const
reverse_iterator rend ()


void swap (Array &)

Detailed Description

1-D array used in linear algebra.

This class implements the concept of vector as used in linear algebra. As such, it is not meant to be used as a container - std::vector should be used instead.


construction of arrays is checked in a number of cases
