RTable.upperBound - return the highest valid index for an RTable's dimension

Calling Sequence

int upperBound( int dim ) throws MapleException

Parameters

dim

-

dimension whose upper bound is returned

Description

• 

The upperBound function returns the highest valid index for the given dimension of the RTable.

• 

The number of dimensions can be accessed with dimensions.  The dimensions are numbered starting from 1.

• 

The lowest valid index for a dimension can be acquired with lowerBound.

Examples

import com.maplesoft.openmaple.*;

import com.maplesoft.externalcall.MapleException;

class Example

{

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

    {

    String mapleArgs[];

    Engine engine;

    RTable a;

    int index[];

    Numeric one;

    int n, i;

    mapleArgs = new String[1];

    mapleArgs[0] = "java";

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

        null, null );

    a = (RTable)engine.evaluate( "Array( 1..3, 1..3, (i,j)->(i*j)+1 ):" );

    n = a.dimensions();

    System.out.println( "Dimensions: "+n );

    for ( i = 1; i <= n; i++ )

    {

        System.out.println( a.lowerBound( i ) );

        System.out.println( a.upperBound( i ) );

    }

    a = (RTable)engine.evaluate( "Array( 10..30, 13..15, 11..17, (i,j)->(i*j)+1 ):" );

    n = a.dimensions();

    System.out.println( "Dimensions: "+n );

    for ( i = 1; i <= n; i++ )

    {

        System.out.println( a.lowerBound( i ) );

        System.out.println( a.upperBound( i ) );

    }

    }

}
