ComplexDoubleRTable.selectImaginary - access the imaginary component of a complex double stored in the ComplexDoubleRTable
Calling Sequence
double selectImaginary( int index[] ) throws MapleException
Parameters
index
-
index of the entry to select
Description
The selectImaginary function returns the imaginary component of the complex double indexed by index in the ComplexDoubleRTable.
The index parameter is an array of integers, one for each dimension of the ComplexDoubleRTable. Each integer must be within the bounds determined by lowerBound and upperBound. The index for dimension is stored in the array at position .
Examples
import com.maplesoft.openmaple.*;
import com.maplesoft.externalcall.MapleException;
class Example
{
public static void main( String notused[] ) throws MapleException
String mapleArgs[];
Engine engine;
ComplexDoubleRTable a1;
int index[];
double e;
mapleArgs = new String[1];
mapleArgs[0] = "java";
engine = new Engine( mapleArgs, new EngineCallBacksDefault(),
null, null );
a1 = (ComplexDoubleRTable)engine.evaluate( "Array( 1..2, 1..2, [[0.1,0.2],[0.3+.3*I,0.4+0.4*I]], datatype=complex[8]):" );
index = new int[2];
index[0] = 1;
index[1] = 1;
e = a1.selectImaginary( index );
System.out.println( "Imag: "+e );
index[0] = 2;
index[1] = 2;
}
Executing this code produces the following output.
Imag: 0.0
Imag: 0.3
Imag: 0.4
