NumericRTable.assign
assign a Numeric into an element of the NumericRTable
Calling Sequence
Parameters
Description
Examples
void assign( int index[], Numeric val ) throws MapleException
index
-
index of the entry to assign
val
value to assign to the list
The assign function assigns the Java Numeric val into the element of the NumericRTable indexed by index.
The index parameter is an array of integers, one for each dimension of the NumericRTable. 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.
As RTables do not have unique representations, elements of an RTable can be assigned to any time.

class Example
{
public static void main( String notused[] ) throws MapleException
String[] mapleArgs = { "java" };
Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );
NumericRTable a1 = (NumericRTable)engine.evaluate( "Array( 1..2, 1..2,[[3^60,3^61],[3^62,3^63]], datatype=sfloat):" );
int[] index = new int[2];
Numeric n = (Numeric)engine.evaluate( "4^60:" );
index[0] = 1;
index[1] = 1;
a1.assign( index, n );
n = (Numeric)engine.evaluate( "4^61:" );
index[0] = 2;
n = (Numeric)engine.evaluate( "4^62:" );
index[1] = 2;
n = (Numeric)engine.evaluate( "4^63:" );
System.out.println( a1 );
}
Executing this code produces the following output.
Array(1..2, 1..2, [[.1329227996e37,.2126764793e38],[.5316911983e37,.8507059173e38]], datatype = sfloat, storage = rectangular, order = Fortran_order)
