RTable.lowerBound

return the lowest valid index for an RTable's dimension

 Calling Sequence int lowerBound( int dim ) throws MapleException

Parameters

 dim - dimension whose lower bound is returned

Description

 • The lowerBound parameter returns the lowest 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 largest valid index for a dimension can be acquired with upperBound.

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 ) ); } } }

Executing this code produces the following output.

 2 1 3 1 3 3 10 30 13 15 11 17
