ComplexDoubleRTable.copyImaginary

create and return a copy of the imaginary values of the current ComplexDoubleRTable

 

Calling Sequence

Description

Examples

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[];

    Engine engine;

    ComplexDoubleRTable a1, iCopy;

    int index[];

    mapleArgs = new String[1];

    mapleArgs[0] = "java";

    engine = new Engine( mapleArgs, new EngineCallBacksDefault(),

        null, null );

    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 );

    iCopy = a1.copyImaginary();

    System.out.println( iCopy );

    index = new int[2];

    index[0] = 1;

    index[1] = 1;

    iCopy.assign( index, 10.0, 10.0 );

    System.out.println( a1 );

    System.out.println( iCopy );

    }

}

Executing this code produces the following output.

Array(1..2, 1..2,
