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 );

    System.out.println( cnRt );

    System.out.println( rCopy );

    }

}

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 =

complex(sfloat), storage = rectangular, order = Fortran_order)

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, [[10.+5.*I,2.+0.*I],[3.+0.*I,4.+0.*I]], datatype =

complex(sfloat), storage = rectangular, order = Fortran_order)
