Detailed Description

The Matrix class.

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

Constructors and destructor.
Assignment operator from scalar.
Resize function.

Definition at line 1193 of file matpackI.h.

Constructor & Destructor Documentation

◆ Matrix() [1/6]

Matrix::Matrix ( )

default

◆ Matrix() [2/6]

Matrix::Matrix	(	Index	r,
		Index	c
	)

Constructor setting size.

This constructor has to set the stride in the row range correctly!

Definition at line 944 of file matpackI.cc.

◆ Matrix() [3/6]

Matrix::Matrix	(	Index	r,
		Index	c,
		Numeric	fill
	)

Constructor setting size and filling with constant value.

Definition at line 950 of file matpackI.cc.

◆ Matrix() [4/6]

Matrix::Matrix ( const ConstMatrixView & m )

Copy constructor from MatrixView.

This automatically sets the size and copies the data.

Definition at line 959 of file matpackI.cc.

References ConstMatrixView::begin(), MatrixView::begin(), copy(), and ConstMatrixView::end().

◆ Matrix() [5/6]

Matrix::Matrix ( const Matrix & m )

Copy constructor from Matrix.

This automatically sets the size and copies the data.

Definition at line 968 of file matpackI.cc.

References ConstMatrixView::mdata, ConstMatrixView::ncols(), and ConstMatrixView::nrows().

◆ Matrix() [6/6]

Matrix::Matrix ( Matrix && v )

inlinenoexcept

Definition at line 1201 of file matpackI.h.

References ConstMatrixView::mdata, and swap().

◆ ~Matrix()

Matrix::~Matrix ( )

virtual

Destructor for Matrix.

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

Definition at line 1083 of file matpackI.cc.

References ConstMatrixView::mdata.

Member Function Documentation

◆ get_raw_data()

Numeric* Matrix::get_raw_data ( )

inline

Definition at line 1220 of file matpackI.h.

References C, copy(), cross3(), debug_matrixview_get_elem(), Zeeman::end(), M, MapToEigen(), MapToEigen4x4(), MapToEigenCol(), MapToEigenRow(), max(), mean(), min(), mult(), mult_general(), operator*(), operator<<(), proj(), transform(), transpose(), and vector_angle().

◆ operator=() [1/4]

Matrix & Matrix::operator= ( const Matrix & m )

Assignment operator from another matrix.

While dimensions of MatrixViews can not be adjusted, dimensions of matrices 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 matrices 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 (Matrix = Matrix). It implicitly covers the cases Matrix=MatrixView, etc, because there is a default constructor for Matrix from MatrixView. (See C++ Primer Plus, page 571ff.)

Parameters

m	The other matrix to assign to this one.

Returns: This matrix, by tradition.

References ConstMatrixView::mdata, ConstMatrixView::ncols(), ConstMatrixView::nrows(), and resize().

◆ operator=() [2/4]

Matrix & Matrix::operator= ( Matrix && x )

noexcept

Move assignment operator from another matrix.

Definition at line 1013 of file matpackI.cc.

References ConstMatrixView::mcr, ConstMatrixView::mdata, and ConstMatrixView::mrr.

◆ operator=() [3/4]

Matrix & Matrix::operator= ( Numeric x )

Assignment operator from scalar.

Assignment operators also seem to be not inherited.

Definition at line 1028 of file matpackI.cc.

References ConstMatrixView::mdata, ConstMatrixView::ncols(), and ConstMatrixView::nrows().

◆ operator=() [4/4]

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

Assignment from a vector.

This copies the data from a VectorView to this MatrixView.

The dimension is adjusted automatically.

Parameters

v	The vector to assign to this matrix.

Returns: This matrix, by tradition.

Author: Stefan Buehler

Date: 2002-12-19

Definition at line 1046 of file matpackI.cc.

References MatrixView::begin(), copy(), ConstVectorView::nelem(), and resize().

◆ resize()

void Matrix::resize	(	Index	r,
		Index	c
	)

Resize function.

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