ComplexNumericRTable.copyReal - create and return a copy of the real values of the current ComplexNumericRTable
Calling Sequence
NumericRTable copyReal( ) throws MapleException
Description
The copyReal function creates and returns a new NumericRTable that contains the real components of each element of the current ComplexNumericRTable.
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.
Examples
import com.maplesoft.openmaple.*;
import com.maplesoft.externalcall.MapleException;
class Example
{
public static void main( String notused[] ) throws MapleException
String mapleArgs[];
Engine engine;
ComplexNumericRTable cnRt, rCopy;
ComplexNumeric cn;
int index[];
mapleArgs = new String[1];
mapleArgs[0] = "java";
engine = new Engine( mapleArgs, new EngineCallBacksDefault(),
null, null );
cnRt = (ComplexNumericRTable)engine.evaluate( "Array( 1..2, 1..2, [[1+I, 2+2*I],[3+3*I, 4+4*I]], datatype=complex(sfloat) ):" );
rCopy = cnRt.copyReal();
System.out.println( cnRt );
System.out.println( rCopy );
index = new int[2];
index[0] = 1;
index[1] = 1;
cn = (ComplexNumeric)engine.evaluate( "10+5*I:" );
rCopy.assign( index, cn );
}
Executing this code produces the following output.
Array(1..2, 1..2, [[1.+1.*I,2.+2.*I],[3.+3.*I,4.+4.*I]], datatype =
complex(sfloat), storage = rectangular, order = Fortran_order)
Array(1..2, 1..2, [[1.+0.*I,2.+0.*I],[3.+0.*I,4.+0.*I]], datatype =
Array(1..2, 1..2, [[10.+5.*I,2.+0.*I],[3.+0.*I,4.+0.*I]], datatype =
