float select( int index[] ) throws MapleException

Parameters

index

-

index of the entry to select

Description

• 

The select function returns the Java float indexed by index in the FloatRTable

• 

The index function is an array of integers, one for each dimension of the FloatRTable.  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;

    DoubleRTable rt;

    double d;

    int index[];

    mapleArgs = new String[1];

    mapleArgs[0] = "java";

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

        null, null );

    rt = (DoubleRTable)engine.evaluate( "Array( 1..2, 1..2, evalf( [[1/3, 1/4],[1/5,1/6]] ), datatype=float[8] ):" );

    index = new int[2];

    index[0] = 1;

    index[1] = 1;

    d = rt.select( index );

    System.out.println( d );

    index[0] = 1;

    index[1] = 2;

    d = rt.select( index );

    System.out.println( d );

    index[0] = 2;

    index[1] = 1;

    d = rt.select( index );

    System.out.println( d );

    index[0] = 2;

    index[1] = 2;

    d = rt.select( index );

    System.out.println( d );

    }

}
