Detailed Description

The Tensor3 class.

This is a Tensor3View that also allocates storage automatically, and deallocates it when it is destroyed. We take all the functionality from Tensor3View. Additionally defined here are:

Constructors and destructor.
Assignment operators.
Resize function.

Constructor & Destructor Documentation

◆ Tensor3() [1/7]

Tensor3::Tensor3 ( )

default

◆ Tensor3() [2/7]

Tensor3::Tensor3	(	Index	p,
		Index	r,
		Index	c
	)

Constructor setting size.

This constructor has to set the strides in the page and row ranges correctly!

Definition at line 556 of file matpackIII.cc.

◆ Tensor3() [3/7]

Tensor3::Tensor3	(	Index	p,
		Index	r,
		Index	c,
		Numeric	fill
	)

Constructor setting size and filling with constant value.

Definition at line 565 of file matpackIII.cc.

References c, and ConstTensor3View::mdata.

◆ Tensor3() [4/7]

Tensor3::Tensor3 ( const ConstTensor3View & m )

Copy constructor from Tensor3View.

This automatically sets the size and copies the data.

Definition at line 577 of file matpackIII.cc.

References Tensor3View::begin(), ConstTensor3View::begin(), copy(), and ConstTensor3View::end().

◆ Tensor3() [5/7]

Tensor3::Tensor3 ( const Tensor3 & m )

Copy constructor from Tensor3.

This automatically sets the size and copies the data.

Definition at line 587 of file matpackIII.cc.

References ConstTensor3View::mdata, ConstTensor3View::ncols(), ConstTensor3View::npages(), and ConstTensor3View::nrows().

◆ Tensor3() [6/7]

Tensor3::Tensor3 ( Tensor3 && v )

inlinenoexcept

Definition at line 347 of file matpackIII.h.

References v.

◆ Tensor3() [7/7]

Tensor3::Tensor3	(	Numeric *	d,
		const Range &	r0,
		const Range &	r1,
		const Range &	r2
	)

inline

Construct from known data

Note that this will call delete on the pointer if it is still valid at the end of the lifetime of this variable

Parameters

[in]	d	- A pointer to some raw data
[in]	r0	- The Range along the first dimension
[in]	r1	- The Range along the second dimension
[in]	r2	- The Range along the third dimension

Definition at line 361 of file matpackIII.h.

References ARTS_ASSERT, and IGRF::r0.

◆ ~Tensor3()

Tensor3::~Tensor3 ( )

virtual

Destructor for Tensor3.

This is important, since Tensor3 uses new to allocate storage.

Definition at line 691 of file matpackIII.cc.

References ConstTensor3View::mdata.

Member Function Documentation

◆ operator=() [1/3]

Tensor3 & Tensor3::operator= ( const Tensor3 & x )

Assignment operator from another tensor.

While dimensions of views can not be adjusted, dimensions of tensors can be adjusted. Hence, the behavior of the assignment operator is different.

In this case the size of the target is automatically adjusted. This is important, so that structures containing tensors are copied correctly.

This is a deviation from the old ARTS paradigm that sizes must match exactly before copying!

Note: It is sufficient to have only this one version of the assignment (Tensor = Tensor). It implicitly covers the cases Tensor=TensorView, etc, because there is a default constructor for Tensor from TensorView. (See C++ Primer Plus, page 571ff.)

Parameters

m	The other tensor to assign to this one.

Returns: This tensor, by tradition.

◆ operator=() [2/3]

Tensor3 & Tensor3::operator= ( Numeric x )

Assignment operator from scalar.

Assignment operators are not inherited.

References ConstTensor3View::mdata, ConstTensor3View::ncols(), ConstTensor3View::npages(), and ConstTensor3View::nrows().

◆ operator=() [3/3]

Tensor3 & Tensor3::operator= ( Tensor3 && x )

noexcept

Move assignment operator from another tensor.

◆ reduce_rank() [1/2]

Vector Tensor3::reduce_rank ( ) &&

inline

Reduce a Tensor3 to a Vector and leave this in an empty state

◆ reduce_rank() [2/2]

template<std::size_t dim0, std::size_t dim1>

Matrix Tensor3::reduce_rank ( ) &&

inline

Reduce a Tensor3 to a Matrix and leave this in an empty state

Definition at line 400 of file matpackIII.h.

References ARTS_ASSERT, Range::get_extent(), ConstTensor3View::mdata, ConstTensor3View::ncols(), ConstTensor3View::npages(), ConstTensor3View::nrows(), IGRF::r0, and Matrix::size().

◆ resize()

void Tensor3::resize	(	Index	p,
		Index	r,
		Index	c
	)

Resize function.

If the size is already correct this function does nothing. All data is lost after resizing! The new tensor is not initialized, so it will contain random values.
