Detailed Description

A constant view of a Vector.

Together with the derived class VectorView this contains the main implementation of a Vector. The class Vector is just a special case of a VectorView which also allocates storage.

Constructor & Destructor Documentation

◆ ~ConstVectorView()

virtual ConstVectorView::~ConstVectorView ( )

inlinevirtual

Destructor.

Definition at line 330 of file matpackI.h.

◆ ConstVectorView() [1/4]

ConstVectorView::ConstVectorView ( const Numeric & a )

A special constructor, which allows to make a ConstVectorView from a scalar.

This one is a bit tricky: We have to cast away the arguments const qualifier, because mdata is not const. This should be safe, since there are no non-const methods for ConstVectorView.

Definition at line 229 of file matpackI.cc.

◆ ConstVectorView() [2/4]

ConstVectorView::ConstVectorView ( )

protected

Default constructor.

This is necessary, so that we can have a default constructor for the derived class Vector.

Definition at line 237 of file matpackI.cc.

Referenced by operator[]().

◆ ConstVectorView() [3/4]

ConstVectorView::ConstVectorView	(	Numeric *	data,
		const Range &	range
	)

protected

Explicit constructor.

This one is used by Vector to initialize its own VectorView part.

Definition at line 245 of file matpackI.cc.

◆ ConstVectorView() [4/4]

ConstVectorView::ConstVectorView	(	Numeric *	data,
		const Range &	p,
		const Range &	n
	)

protected

Recursive constructor.

This is used to construct sub ranges from sub ranges. That means that the new range has to be interpreted relative to the original range. The new range may contain -1 for the extent which acts as a joker. However, the used Range constructor converts this to an explicit range, consistent with the original Range.

Parameters

*data	The actual data.
p	Previous range.
n	New Range.

◆ begin()

◆ nelem()

Index ConstVectorView::nelem ( ) const

Returns the number of elements.

The names ‘size’ and ‘length’ are already used by STL functions returning size_t. To avoid confusion we choose the name ‘nelem’. This is also more consistent with ‘nrow’ and ‘ncol’ for matrices.

The value range of long, which is used to store the index is on a PC from -2147483648 to 2147483647. This means that a 15GB large array of float can be addressed with this index. So the extra bit that size_t has compared to long is not needed.

Matrix Vector multiplication.

y = M*x. Note that the order is different from MTL, output comes first! Dimensions of y, M, and x must match. No memory reallocation takes place, only the data is copied. Using this function on overlapping MatrixViews belonging to the same Matrix will lead to unpredictable results. In particular, this means that A and B must not be the same matrix! The implementation here is different from the other multiplication routines. It does not use iterators but a more drastic approach to gain maximum performance.
