Detailed Description

The ComplexVectorView class.

This contains the main implementation of a complex vector. The class ComplexVector is just a special case of subvector which also allocates storage.

Unfortunately, names of element functions of derived classes hide the names of the original class, even if the arguments are different. This means that we have to redefine those element functions that can have different arguments, for example the constant index operators and iterators.

◆ ComplexVectorView() [6/7]

◆ ComplexVectorView() [7/7]

ComplexVectorView::ComplexVectorView	(	Complex *	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.

◆ operator=() [1/10]

ComplexVectorView & ComplexVectorView::operator= ( const ConstComplexVectorView & v )

Assignment operator.

This copies the data from another VectorView t o this Complex*VectorView. Dimensions must agree! Resizing would destroy the selection that we might have done in this VectorView by setting its range.

Definition at line 193 of file complex.cc.

References ConstComplexVectorView::begin(), copy(), ConstComplexVectorView::end(), Range::mextent, and ConstComplexVectorView::mrange.

Referenced by ComplexVector::operator=().

◆ operator=() [2/10]

ComplexVectorView & ComplexVectorView::operator= ( const ComplexVectorView & v )

Assignment from ComplexVectorView to ComplexVectorView.

This is a tricky one. The problem is that since ComplexVectorView is derived from ConstComplexVectorView, a default = operator is generated by the compiler, which does not do what we want. So we need this one to override the default.

Definition at line 210 of file complex.cc.

References ConstComplexVectorView::begin(), begin(), copy(), end(), Range::mextent, and ConstComplexVectorView::mrange.

◆ operator=() [3/10]

ComplexVectorView & ComplexVectorView::operator= ( const ComplexVector & v )

Assignment from ComplexVector.

This is important to avoid a bug when assigning a Vector to a Complex*VectorView.

Definition at line 223 of file complex.cc.

References ConstComplexVectorView::begin(), begin(), copy(), end(), Range::mextent, and ConstComplexVectorView::mrange.

◆ operator=() [4/10]

ComplexVectorView & ComplexVectorView::operator= ( const Array< Complex > & v )

Assignment operator from Array<Complex>.

This copies the data from an Array<Complex> to this VectorView. Dimensions must agree! Resizing would destroy the selection that we might have done in this VectorView by setting its range.

Array<Complex> can be useful to collect things in, because there is a .push_back method for it. Then, after collecting we usually have to transfer the content to a Vector. With this assignment operator that's easy.

Definition at line 1534 of file complex.cc.

References i, and Array< base >::nelem().

◆ operator=() [5/10]

ComplexVectorView & ComplexVectorView::operator= ( Complex x )

Assigning a scalar to a ComplexVectorView will set all elements to this value.

Definition at line 236 of file complex.cc.

References ConstComplexVectorView::begin(), copy(), and ConstComplexVectorView::end().

◆ operator=() [6/10]

ComplexVectorView& ComplexVectorView::operator= ( const ConstVectorView & v )

◆ operator=() [7/10]

ComplexVectorView& ComplexVectorView::operator= ( const VectorView & v )

◆ operator=() [8/10]

◆ operator=() [9/10]

ComplexVectorView& ComplexVectorView::operator= ( const Array< Numeric > & v )

◆ operator=() [10/10]

ComplexVectorView& ComplexVectorView::operator= ( Numeric x )

◆ operator[]() [1/2]

Complex& ComplexVectorView::operator[] ( Index n )

inline

Plain Index operator.

Definition at line 387 of file complex.h.

References n.

◆ operator[]() [2/2]

ComplexVectorView ComplexVectorView::operator[] ( const Range & r )

Index operator for subrange.

We have to also account for the case, that *this is already a subrange of a Vector. This allows correct recursive behavior.

Definition at line 173 of file complex.cc.

References ConstComplexVectorView::ComplexVectorView, ConstComplexVectorView::mdata, and ConstComplexVectorView::mrange.

◆ real()

VectorView ComplexVectorView::real ( )

inline

Get a view of the real part of the vector.
