ComplexNumericRTable.copyImaginary
create and return a copy of the imaginary values of the current ComplexNumericRTable
Calling Sequence
Description
Examples
NumericRTable copyImaginary( ) throws MapleException
The copyImaginary function creates and returns a new NumericRTable that contains the imaginary 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.

{
public static void main( String notused[] ) throws MapleException
String[] mapleArgs = { "java" };
Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );
ComplexNumericRTable cnRt = (ComplexNumericRTable)engine.evaluate( "Array( 1..2, 1..2, [[1+I, 2+2*I],[3+3*I, 4+4*I]], datatype=complex(sfloat) ):" );
ComplexNumericRTable iCopy = cnRt.copyImaginary();
System.out.println( cnRt );
System.out.println( iCopy );
int[] index = new int[2];
index[0] = 1;
index[1] = 1;
ComplexNumeric cn = (ComplexNumeric)engine.evaluate( "10+5*I:" );
iCopy.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 =
