AlgebraicRTable.select

access an Algebraic stored in the AlgebraicRTable

 Calling Sequence Algebraic select( int index[] ) throws MapleException

Parameters

 index - index of the entry to select

Description

 • The select function returns the Algebraic object indexed by index in the AlgebraicRTable.
 • index is an array of integers, one for each dimension of the AlgebraicRTable.  Each integer must be within the bounds determined by lowerBound and upperBound.  The index for dimension $i$ is stored in the array at position $i-1$.

Examples

 import com.maplesoft.openmaple.*; import com.maplesoft.externalcall.MapleException; class Example { public static void main( String notused[] ) throws MapleException { String[] mapleArgs = { "java" }; Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null ); AlgebraicRTable a1 = (AlgebraicRTable)engine.evaluate( "Array( 1..2, 1..2, [[a,b],[c,d]]):" ); int[] 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 ) ); } }
