Description

• 

The select function returns the Java int indexed by index in the IntRTable

The index parameter is an array of integers, one for each dimension of the IntRTable.  Each integer must be within the bounds determined by lowerBound and upperBound.  The index for dimension i is stored in the array at position i1.

Examples

import com.maplesoft.openmaple.*;

import com.maplesoft.externalcall.MapleException;

class Example

{

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

    {

    String mapleArgs[];

    Engine engine;

    IntRTable a1;

    int index[];

    mapleArgs = new String[1];

    mapleArgs[0] = "java";

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

        null, null );

    a1 = (IntRTable)engine.evaluate( "Array( 1..2, 1..2, [[2^18,2^19],[2^20,2^21]], datatype=integer[4]):" );

    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 ) );
