index of the entry to select

Description

• 

The select function returns the Java Numeric indexed by index in the NumericRTable

The index parameter is an array of integers, one for each dimension of the NumericRTable. 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;

    NumericRTable a1;

    int index[];

    mapleArgs = new String[1];

    mapleArgs[0] = "java";

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

        null, null );

    a1 = (NumericRTable)engine.evaluate( "Array( 1..2, 1..2, [[2^100,2^101],[2^102, 2^103]], datatype=sfloat ):" );

    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 ) );

    }
