ComplexDoubleRTable.copyImaginary

create and return a copy of the imaginary values of the current ComplexDoubleRTable Calling Sequence ComplexDoubleRTable copyImaginary( ) throws MapleException Description

 • The copyImaginary function creates and returns a new ComplexDoubleRTable that contains the imaginary 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. Examples

 import com.maplesoft.openmaple.*; import com.maplesoft.externalcall.MapleException; class Example { 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):" ); System.out.println( a1 ); ComplexDoubleRTable iCopy = a1.copyImaginary(); System.out.println( iCopy ); int[] index = new int; index = 1; index = 1; iCopy.assign( index, 10.0, 10.0 ); System.out.println( a1 ); System.out.println( iCopy ); } }

Executing this code produces the following output.
