Description

• 

The select function returns the Java long indexed by index in the LongRTable

Examples

import com.maplesoft.openmaple.*;

import com.maplesoft.externalcall.MapleException;

class Example

{

    public static void main( String notused[] ) throws MapleException

    {

    String mapleArgs[];

    Engine engine;

    LongRTable a1;

    int index[];

    mapleArgs = new String[1];

    mapleArgs[0] = "java";

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

        null, null );

    a1 = (LongRTable)engine.evaluate( "Array( 1..2, 1..2, [[2^45,2^50],[2^55,2^60]], datatype=integer[8]):" );

    index = new int[2];

    index[0] = 1;

    index[1] = 1;

    System.out.println( a1.select( index ) );

    index[0] = 2;

    index[1] = 1;

    System.out.println( a1.select( index ) );

    index[0] = 1;

    index[1] = 2;

    System.out.println( a1.select( index ) );

    index[0] = 2;

    index[1] = 2;

    System.out.println( a1.select( index ) );

    }
