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.DMatrixTranspose.__init__ ( DMatrixTranspose mt )

Contructs a copy of the DMatrixTranspose instance mt.

Parameters

mt	The `DMatrixTranspose` instance to copy.

◆ init() [2/2]

None CDPL.Math.DMatrixTranspose.__init__ ( DMatrixExpression m )

Constructs the transpose view proxy referring to m.

Parameters

m	The wrapped matrix.

Member Function Documentation

◆ getObjectID()

int CDPL.Math.DMatrixTranspose.getObjectID ( )

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

Different Python DMatrixTranspose 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 DMatrixTranspose 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.
