ComplexDoubleRTable.copyReal
create and return a copy of the real values of the current ComplexDoubleRTable
Calling Sequence
Description
Examples
DoubleRTable copyReal( ) throws MapleException
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.

{
public static void main( String notused[] ) throws MapleException
String[] mapleArgs = { "java" };
Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );
ComplexDoubleRTable a1 = (ComplexDoubleRTable)engine.evaluate( "Array( 1..2, 1..2, [[0.1,0.2],[0.3+.3*I,0.4+0.4*I]], datatype=complex[8]):" );
System.out.println( a1 );
ComplexDoubleRTable iCopy = a1.copyReal();
System.out.println( iCopy );
int[] index = new int[2];
index[0] = 1;
index[1] = 1;
iCopy.assign( index, 10.0, 10.0 );
}
Executing this code produces the following output.
Array(1..2, 1..2,
[[.100000000000000004+0.*I,.200000000000000010+0.*I],[.299999999999999988+.299999999999999988*I,.400000000000000022+.400000000000000022*I]],
datatype = complex[8], storage = rectangular, order = Fortran_order)
