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.

Definition at line 339 of file matpackIII.h.

Constructor & Destructor Documentation

◆ Tensor3() [1/6]

Tensor3::Tensor3 ( )

default

◆ Tensor3() [2/6]

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 562 of file matpackIII.cc.

◆ Tensor3() [3/6]

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

Constructor setting size and filling with constant value.

Definition at line 571 of file matpackIII.cc.

◆ Tensor3() [4/6]

Tensor3::Tensor3 ( const ConstTensor3View & m )

Copy constructor from Tensor3View.

This automatically sets the size and copies the data.

Definition at line 583 of file matpackIII.cc.

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

◆ Tensor3() [5/6]

Tensor3::Tensor3 ( const Tensor3 & m )

Copy constructor from Tensor3.

This automatically sets the size and copies the data.

Definition at line 593 of file matpackIII.cc.

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

◆ Tensor3() [6/6]

Tensor3::Tensor3 ( Tensor3 && v )

inlinenoexcept

Definition at line 347 of file matpackIII.h.

References C, copy(), debug_tensor3view_get_elem(), Zeeman::end(), max(), ConstTensor3View::mdata, min(), mult(), operator<<(), swap(), and transform().

◆ ~Tensor3()

Tensor3::~Tensor3 ( )

virtual

Destructor for Tensor3.

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

Definition at line 697 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.

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

◆ operator=() [2/3]

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

noexcept

Move assignment operator from another tensor.

Definition at line 639 of file matpackIII.cc.

References ConstTensor3View::mcr, ConstTensor3View::mdata, ConstTensor3View::mpr, and ConstTensor3View::mrr.

◆ operator=() [3/3]

Tensor3 & Tensor3::operator= ( Numeric x )

Assignment operator from scalar.

Assignment operators are not inherited.

Definition at line 656 of file matpackIII.cc.

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

◆ 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.

Definition at line 664 of file matpackIII.cc.
