RTable.copy
create and return a copy of the current RTable
Calling Sequence
Description
Examples
RTable copy( ) throws MapleException
The copy function creates and returns a new RTable that contains the same data as the current RTable.
As RTables do not have unique representations, the returned copy is a different Maple object from the original. Changes to the copy do not affect the original.

class Example
{
public static void main( String notused[] ) throws MapleException
String[] mapleArgs = { "java" };
Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );
RTable a, b;
int index[];
Numeric one;
a = (RTable)engine.evaluate( "Array( 1..3, 1..3, (i,j)->(i*j)+1 ):" );
b = a.copy();
index = new int[3];
one = engine.newNumeric( 1 );
index[0] = 1;
index[1] = 1;
((AlgebraicRTable)b).assign( index, one );
index[0] = 2;
index[1] = 2;
index[0] = 3;
index[1] = 3;
System.out.println( a );
System.out.println( b );
}
Executing this code produces the following output.
Array(1..3, 1..3, [[2,3,4],[3,5,7],[4,7,10]], datatype = anything, storage = rectangular, order = Fortran_order)
Array(1..3, 1..3, [[1,3,4],[3,1,7],[4,7,1]], datatype = anything, storage = rectangular, order = Fortran_order)
