Constructor & Destructor Documentation

◆ __init__() [1/2]

None CDPL.Math.ConstULMatrixTranspose.__init__ ( ConstULMatrixTranspose  mt)

Contructs a copy of the ConstULMatrixTranspose instance mt.

Parameters
mtThe ConstULMatrixTranspose instance to copy.

◆ __init__() [2/2]

None CDPL.Math.ConstULMatrixTranspose.__init__ ( ConstULMatrixExpression  e)

Contructs the ConstULMatrixTranspose instance.

Parameters
e

Member Function Documentation

◆ getObjectID()

int CDPL.Math.ConstULMatrixTranspose.getObjectID ( )

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

Different Python ConstULMatrixTranspose 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 ConstULMatrixTranspose 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.ConstULMatrixTranspose.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.ConstULMatrixTranspose.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.ConstULMatrixTranspose.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()

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

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

Parameters
iThe zero-based row index in the transposed view.
jThe zero-based column index in the transposed view.
Returns
The wrapped matrix value m(j, i).

◆ toArray()

object CDPL.Math.ConstULMatrixTranspose.toArray ( )

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

Returns
The generated numpy.ndarray object.
