Constructor & Destructor Documentation

◆ __init__() [1/2]

None CDPL.Math.ConstDMatrixTranspose.__init__ ( ConstDMatrixTranspose  mt)

Initializes a copy of the ConstDMatrixTranspose instance mt.

Parameters
mtThe ConstDMatrixTranspose instance to copy.

◆ __init__() [2/2]

None CDPL.Math.ConstDMatrixTranspose.__init__ ( ConstDMatrixExpression  e)

Initializes the ConstDMatrixTranspose instance.

Parameters
e

Member Function Documentation

◆ getObjectID()

int CDPL.Math.ConstDMatrixTranspose.getObjectID ( )

Returns the numeric identifier (ID) of the wrapped C++ class instance.

Different Python ConstDMatrixTranspose instances may reference the same underlying C++ class instance. The commonly used Python expression a is not b thus cannot tell reliably whether the two ConstDMatrixTranspose instances a and b reference different C++ objects. The numeric identifier returned by this method allows to correctly implement such an identity test via the simple expression a.getObjectID() != b.getObjectID().

Returns
The numeric ID of the internally referenced C++ class instance.

◆ getSize1()

int CDPL.Math.ConstDMatrixTranspose.getSize1 ( )

Returns the number of rows of the transpose view (= number of columns of the wrapped matrix).

Returns
The number of rows.

◆ getSize2()

int CDPL.Math.ConstDMatrixTranspose.getSize2 ( )

Returns the number of columns of the transpose view (= number of rows of the wrapped matrix).

Returns
The number of columns.

◆ isEmpty()

bool CDPL.Math.ConstDMatrixTranspose.isEmpty ( )

Tells whether the view is empty (the wrapped matrix has zero rows or zero columns).

Returns
True if the wrapped matrix is empty, and False otherwise.

◆ getData()

ConstDMatrixExpression CDPL.Math.ConstDMatrixTranspose.getData ( )

Returns a reference to the wrapped matrix (via its stored closure).

Returns
A reference to the wrapped matrix closure.

◆ __call__()

float CDPL.Math.ConstDMatrixTranspose.__call__ ( int  i,
int  j 
)

Returns a reference to the wrapped matrix's element at (j, i).

Parameters
iThe zero-based row index in the transposed view.
jThe zero-based column index in the transposed view.
Returns
A reference to m(j, i).

◆ __eq__() [1/2]

bool CDPL.Math.ConstDMatrixTranspose.__eq__ ( ConstDMatrixTranspose  mt)

Returns the result of the comparison operation self == mt.

Parameters
mtThe ConstDMatrixTranspose instance to be compared with.
Returns
The result of the comparison operation.

◆ __eq__() [2/2]

bool CDPL.Math.ConstDMatrixTranspose.__eq__ ( ConstDMatrixExpression  e)

Returns the result of the comparison operation self == e.

Parameters
eThe ConstDMatrixExpression instance to be compared with.
Returns
The result of the comparison operation.

◆ __ne__() [1/2]

bool CDPL.Math.ConstDMatrixTranspose.__ne__ ( ConstDMatrixTranspose  mt)

Returns the result of the comparison operation self != mt.

Parameters
mtThe ConstDMatrixTranspose instance to be compared with.
Returns
The result of the comparison operation.

◆ __ne__() [2/2]

bool CDPL.Math.ConstDMatrixTranspose.__ne__ ( ConstDMatrixExpression  e)

Returns the result of the comparison operation self != e.

Parameters
eThe ConstDMatrixExpression instance to be compared with.
Returns
The result of the comparison operation.

◆ __str__()

str CDPL.Math.ConstDMatrixTranspose.__str__ ( )

Returns a string representation of the ConstDMatrixTranspose instance.

Returns
The generated string representation.

◆ __add__()

ConstDMatrixExpression CDPL.Math.ConstDMatrixTranspose.__add__ ( ConstDMatrixExpression  e)
