ComplexNumericRTable.assign
assign a complex double into a ComplexNumericRTable
Calling Sequence
Parameters
Description
Examples
void assign( int index[], ComplexNumeric val ) throws MapleException
index
-
the index of the entry to assign
val
the ComplexNumeric
The assign function assigns the ComplexNumeric val into the element of the ComplexNumericRTable indexed by index.
The index parameter is an array of integers, one for each dimension of the ComplexNumericRTable. 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 at any time.

class Example
{
public static void main( String notused[] ) throws MapleException
String[] mapleArgs = { "java" };
Engine engine = new Engine( mapleArgs, new EngineCallBacksDefault(), null, null );
ComplexNumericRTable cnRt = (ComplexNumericRTable)engine.evaluate( "Array( 1..2, 1..2, [[1+I, 2+2*I],[3+3*I, 4+4*I]], datatype=complex(sfloat) ):" );
int[] index = new int[2];
index[0] = 1;
index[1] = 1;
ComplexNumeric cn = (ComplexNumeric)engine.evaluate( "10+5*I:" );
cnRt.assign( index, cn );
index[1] = 2;
cn = (ComplexNumeric)engine.evaluate( "20+10*I:" );
index[0] = 2;
cn = (ComplexNumeric)engine.evaluate( "30+15*I:" );
cn = (ComplexNumeric)engine.evaluate( "40+20*I:" );
System.out.println( cnRt );
}
Executing this code produces the following output.
Array(1..2, 1..2, [[10.+5.*I,20.+10.*I],[30.+15.*I,40.+20.*I]], datatype =
complex(sfloat), storage = rectangular, order = Fortran_order)
