ComplexDoubleRTable.copyReal - create and return a copy of the real values of the current ComplexDoubleRTable
|
|
Calling Sequence
|
|
DoubleRTable copyReal( ) throws MapleException
|
|
|
Description
|
|
|
•
|
The copyReal function creates and returns a new DoubleRTable that contains the real components of each element of the current ComplexDoubleRTable.
|
|
•
|
As RTables do not have unique representations, the returned copy is a different Maple object from the original. Therefore changes to the copy do not affect the original.
