access a ComplexNumeric stored in the ComplexNumericRTable
Calling Sequence
Parameters
Description
Examples
ComplexNumeric select( int index[] ) throws MapleException
index
-
index of the entry to select
The select function returns the ComplexNumeric indexed by index in the ComplexNumericRTable.
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.

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 = cnRt.select( index );
System.out.println( cn );
index[1] = 2;
cn = cnRt.select( index );
index[0] = 2;
}
Executing this code produces the following output.
1.+1.*I
2.+2.*I
3.+3.*I
4.+4.*I
