Detailed Description

This is the yat interface to GSL vector.

This is an interface class for vectors containing the const interface. For mutable functionality see VectorMutable.

Member Typedef Documentation

typedef const double& theplu::yat::utility::VectorBase::const_reference

const_reference type is const double&

Since: New in yat 0.5

typedef double theplu::yat::utility::VectorBase::value_type

value_type is double

Since: New in yat 0.5

Constructor & Destructor Documentation

virtual theplu::yat::utility::VectorBase::~VectorBase ( void )

virtual

The destructor.

Member Function Documentation

const_iterator theplu::yat::utility::VectorBase::begin ( void ) const

Returns: read-only iterator to start of VectorBase

const_iterator theplu::yat::utility::VectorBase::end ( void ) const

Returns: read-only iterator to end of VectorBase

bool theplu::yat::utility::VectorBase::equal	(	const VectorBase &	,
		const double	precision = `0`
	)		const

Check whether VectorBases are equal within a user defined precision, set by precision.

Returns: True if each element deviates less or equal than d. If any VectorBase contain a NaN, false is always returned.

See Also: operator== and operator!=

const gsl_vector* theplu::yat::utility::VectorBase::gsl_vector_p ( void ) const

Returns: A const pointer to the internal GSL vector,

virtual bool theplu::yat::utility::VectorBase::isview ( void ) const

pure virtual

Check if the vector object is a view (sub-vector) to another vector.

Returns: True if the object is a view, false othwerwise.

Implemented in theplu::yat::utility::VectorView, theplu::yat::utility::VectorMutable, theplu::yat::utility::Vector, and theplu::yat::utility::VectorConstView.

bool theplu::yat::utility::VectorBase::operator!= ( const VectorBase & ) const

Comparison operator. Takes linear time.

Checks are performed with exact matching, i.e., rounding off effects may destroy comparison. Use the equal function for comparing elements within a user defined precision.

Returns: False if all elements are equal otherwise true.

See Also: equal(const VectorBase&, const double precision=0)

const double& theplu::yat::utility::VectorBase::operator() ( size_t i ) const

Element access operator.

Returns: Const reference to element i.

Exceptions

If	GSL range checks are enabled in the underlying GSL library a GSL_error exception is thrown if either index is out of range.

double theplu::yat::utility::VectorBase::operator* ( const VectorBase & ) const

Returns: The dot product.

bool theplu::yat::utility::VectorBase::operator== ( const VectorBase & ) const

Comparison operator. Takes linear time.

Checks are performed with exact matching, i.e., rounding off effects may destroy comparison. Use the equal function for comparing elements within a user defined precision.

Returns: True if all elements are equal otherwise false.

See Also: equal(const VectorBase&, const double precision=0)

size_t theplu::yat::utility::VectorBase::size ( void ) const

Returns: number of elements in the VectorBase.

Friends And Related Function Documentation

bool isnull ( const VectorBase & )

Returns: True if all elements in the VectorBase is zero, false othwerwise.

double max ( const VectorBase & )

Returns: The maximum value of the VectorBase.

size_t max_index ( const VectorBase & )

Returns: The index to the maximum value of the VectorBase.

Note: Lower index has precedence.

double min ( const VectorBase & )

Returns: The minimum value of the VectorBase.

size_t min_index ( const VectorBase & )

Returns: The index to the minimum value of the VectorBase.

Note: Lower index has precedence.

bool nan	(	const VectorBase &	templat,
		Vector &	flag
	)

The flag VectorBase is changed to contain 1's and 0's only. A 1 means that the corresponding element in the templat VectorBase is valid and a zero means that the corresponding element is a NaN.

Note: Space for vector flag is reallocated to fit the size of VectorBase templat if sizes mismatch.

Returns: True if the templat VectorBase contains at least one NaN.

std::ostream & operator<<	(	std::ostream &	s,
		const VectorBase &	v
	)

Elements in VectorBase v are sent to ostream s and separated with the fill character of stream s, s.fill(). If you, for example, want to print the VectorBase v with the elements separated by a ':', you do so by:

s << setfill(':') << v;

void sort_index	(	std::vector< size_t > &	sort_index,
		const VectorBase &	invec
	)

Create a vector sort_index containing the indeces of elements in a another VectorBase invec. The elements of sort_index give the index of the VectorBase element which would have been stored in that position if the VectorBase had been sorted in place. The first element of sort_index gives the index of the least element in invec, and the last element of sort_index gives the index of the greatest element in invec . The VectorBase invec is not changed.

void sort_largest_index	(	std::vector< size_t > &	sort_index,
		size_t	k,
		const VectorBase &	invec
	)

void sort_smallest_index	(	std::vector< size_t > &	sort_index,
		size_t	k,
		const VectorBase &	invec
	)

double sum ( const VectorBase & )

Returns: The sum.
