DoubleRTable.assign - assign a double into an element of the DoubleRTable
Calling Sequence
void assign( int index[], double val ) throws MapleException
Parameters
index
-
index of the entry to assign
val
value to assign into the list
Description
The assign function assigns the Java double val into the element of the DoubleRTable indexed by index.
The index parameter is an array of integers, one for each dimension of the DoubleRTable. Each integer must be within the bounds determined by lowerBound and upperBound. The index for dimension is stored in the array at position .
As RTables do not have unique representations, elements of an RTable can be assigned to at any time.
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;
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;
rt.assign( index, 2./3 );
index[1] = 2;
rt.assign( index, 2./4 );
index[0] = 2;
rt.assign( index, 2./5 );
rt.assign( index, 2./6 );
System.out.println( rt );
}
Executing this code produces the following output.
Array(1..2, 1..2, [[.666666666666666630,.500000000000000000],[.400000000000000022,.333333333333333315]], datatype = float[8], storage = rectangular, order = Fortran_order)
