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.

◆ getElement()

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

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

Parameters

i	The zero-based row index in the transposed view.
j	The zero-based column index in the transposed view.

Returns: The wrapped matrix value m(j, i).

◆ toArray()

object CDPL.Math.ConstDMatrixTranspose.toArray ( )

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

Returns: The generated numpy.ndarray object.
