Member Function Documentation

resize()

None CDPL.Math.ULMatrix.resize	(	int	m,
		int	n,
		bool	preserve = True,
		int	v = 0
	)

Parameters

m
n
preserve
v

clear()

None CDPL.Math.ULMatrix.clear

(

int

v = 0

)

Parameters

v

getObjectID()

int CDPL.Math.ULMatrix.getObjectID

(

)

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

Different Python ULMatrix 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 ULMatrix 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.
