Member Function Documentation

◆ getObjectID()

int CDPL.Math.ConstLMatrixExpression.getObjectID ( )

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

Different Python ConstLMatrixExpression 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 ConstLMatrixExpression 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.ConstLMatrixExpression.getSize1 ( )

Returns the number of rows.

Returns: The number of rows.

◆ getSize2()

int CDPL.Math.ConstLMatrixExpression.getSize2 ( )

Returns the number of columns.

Returns: The number of columns.

◆ isEmpty()

bool CDPL.Math.ConstLMatrixExpression.isEmpty ( )

Tells whether the matrix is empty.

Returns: True if the underlying storage holds no elements, and False otherwise.

◆ getElement()

int CDPL.Math.ConstLMatrixExpression.getElement	(	int	i,
		int	j
	)

Returns the element at (i, j).

Parameters

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

Returns: The value of the element.

Exceptions

Base.IndexError if either index is out of range.

◆ toArray()

object CDPL.Math.ConstLMatrixExpression.toArray ( )

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

Returns: The generated numpy.ndarray object.

See also: [NUMPY]

◆ call()

int CDPL.Math.ConstLMatrixExpression.__call__	(	int	i,
		int	j
	)

Returns the element at (i, j).

Parameters

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

Returns: The value of the element.

Exceptions

Base.IndexError if either index is out of range.

◆ getitem()

int CDPL.Math.ConstLMatrixExpression.__getitem__ ( tuple ij )
