ComplexNumericRTable.copyReal

create and return a copy of the real values of the current ComplexNumericRTable

 

Calling Sequence

Description

Examples

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 = { "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 rCopy = cnRt.copyReal();

        System.out.println( cnRt );

        System.out.println( rCopy );

        int[] index = new int[2];

        index[0] = 1;

        index[1] = 1;

        ComplexNumeric 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)
