FloatRTable.assign
assign a float into an element of the FloatRTable
Calling Sequence
Parameters
Description
Examples
void assign( int index[], float val ) throws MapleException
index
-
index of the entry to assign
val
value to assign into the list
The assign function assigns the Java float val into the element of the FloatRTable indexed by index.
The index parameter is an array of integers, one for each dimension of the FloatRTable. 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 );
FloatRTable a1 = (FloatRTable)engine.evaluate( "Array( 1..2, 1..2, [[1.5,2.5],[3.5,4.5]], datatype=float[4]):" );
int[] index = new int[2];
float e = (float)11.5;
index[0] = 1;
index[1] = 1;
a1.assign( index, e );
e = (float)12.5;
index[0] = 2;
e = (float)13.5;
index[1] = 2;
e = (float)14.5;
System.out.println( a1 );
}
Executing this code produces the following output.
Array(1..2, 1..2, [[11.5000000,13.5000000],[12.5000000,14.5000000]], datatype = float[4], storage = rectangular, order = Fortran_order)
