Detailed Description

The ComplexMatrix class.

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

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

Definition at line 858 of file complex.h.

Constructor & Destructor Documentation

◆ ComplexMatrix() [1/6]

ComplexMatrix::ComplexMatrix ( )

default

◆ ComplexMatrix() [2/6]

ComplexMatrix::ComplexMatrix	(	Index	r,
		Index	c
	)

Constructor setting size.

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

Definition at line 1350 of file complex.cc.

◆ ComplexMatrix() [3/6]

ComplexMatrix::ComplexMatrix	(	Index	r,
		Index	c,
		Complex	fill
	)

Constructor setting size and filling with constant value.

Definition at line 1356 of file complex.cc.

◆ ComplexMatrix() [4/6]

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

Constructor setting size and filling with constant value.

Definition at line 1365 of file complex.cc.

◆ ComplexMatrix() [5/6]

ComplexMatrix::ComplexMatrix ( const ConstComplexMatrixView & m )

Copy constructor from MatrixView.

This automatically sets the size and copies the data.

Definition at line 1375 of file complex.cc.

References ComplexMatrixView::begin(), ConstComplexMatrixView::begin(), copy(), and ConstComplexMatrixView::end().

◆ ComplexMatrix() [6/6]

ComplexMatrix::ComplexMatrix ( const ComplexMatrix & m )

Copy constructor from Matrix.

This automatically sets the size and copies the data.

Definition at line 1384 of file complex.cc.

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

◆ ~ComplexMatrix()

ComplexMatrix::~ComplexMatrix ( )

virtual

Destructor for Matrix.

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

◆ inv()

ComplexMatrix & ComplexMatrix::inv ( const lapack_help::Inverse< Complex > & help = lapack_help::Inverse<Complex>{0} )

Definition at line 1488 of file complex.cc.

◆ operator=() [1/3]

ComplexMatrix & ComplexMatrix::operator= ( Complex x )

Assignment operator from scalar.

Assignment operators also seem to be not inherited.

Definition at line 1427 of file complex.cc.

References ComplexMatrixView::begin(), copy(), ComplexMatrixView::end(), and ARTS::Var::x().

◆ operator=() [2/3]

ComplexMatrix & ComplexMatrix::operator= ( ComplexMatrix 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.

◆ operator=() [3/3]

ComplexMatrix & ComplexMatrix::operator= ( const ConstComplexVectorView & 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.

Definition at line 1445 of file complex.cc.

◆ resize()

void ComplexMatrix::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.
