Detailed Description

Mutable view adapter that exposes the transpose of a matrix M as a matrix expression ( \( (i, j) \to M(j, i) \)).

Constructor & Destructor Documentation

◆ __init__() [1/2]

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

Contructs a copy of the FMatrixTranspose instance mt.

Parameters
mtThe FMatrixTranspose instance to copy.

◆ __init__() [2/2]

None CDPL.Math.FMatrixTranspose.__init__ ( FMatrixExpression  m)

Constructs the transpose view proxy referring to m.

Parameters
mThe wrapped matrix.

Member Function Documentation

◆ getObjectID()

int CDPL.Math.FMatrixTranspose.getObjectID ( )

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

Different Python FMatrixTranspose 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 FMatrixTranspose 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.
