Detailed Description

Constructor & Destructor Documentation

◆ init() [1/2]

None CDPL.Math.ConstLowerTriangularDMatrixAdapter.__init__ ( ConstLowerTriangularDMatrixAdapter ta )

Contructs a copy of the ConstLowerTriangularDMatrixAdapter instance ta.

Parameters

ta	The `ConstLowerTriangularDMatrixAdapter` instance to copy.

Member Function Documentation

◆ getObjectID()

int CDPL.Math.ConstLowerTriangularDMatrixAdapter.getObjectID ( )

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

Different Python ConstLowerTriangularDMatrixAdapter 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 ConstLowerTriangularDMatrixAdapter 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.ConstLowerTriangularDMatrixAdapter.getSize1 ( )

Returns the number of rows of the wrapped matrix.

Returns: The row count.

◆ getSize2()

int CDPL.Math.ConstLowerTriangularDMatrixAdapter.getSize2 ( )

Returns the number of columns of the wrapped matrix.

Returns: The column count.

◆ isEmpty()

bool CDPL.Math.ConstLowerTriangularDMatrixAdapter.isEmpty ( )

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

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

◆ getElement()

float CDPL.Math.ConstLowerTriangularDMatrixAdapter.getElement	(	int	i,
		int	j
	)

Returns the value of element (i, j) as seen through the lower triangular policy (off-policy entries return the fill value zero).

Parameters

i	The zero-based row index.
j	The zero-based column index.

Returns: The element value as defined by the lower triangular-view policy.

◆ toArray()

object CDPL.Math.ConstLowerTriangularDMatrixAdapter.toArray ( )

Converts the ConstLowerTriangularDMatrixAdapter instance into a corresponding numpy.ndarray object.

Returns: The generated numpy.ndarray object.

◆ call()

float CDPL.Math.ConstLowerTriangularDMatrixAdapter.__call__	(	int	i,
