Member Function Documentation

◆ resize()

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

Resizes the matrix to m×n elements.

Parameters
mThe new row count.
nThe new column count.
preserveIf True, existing element values at indices that remain valid are kept. If False, all elements are set to v.
vThe fill value for newly added elements (or for all elements when preserve is False).

◆ clear()

None CDPL.Math.ULMatrix.clear ( int   v = 0)

Sets every element of the matrix to the value v.

Parameters
vThe fill value.

◆ 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.
