java.lang.Object
   |
   +----Jampack.Z1
public class Z1
extends Object
Z1 implements a one-dimensional array of complex numbers as a two arrays of type double. The addressing is zero based. It is necessary to provided one-dimensional complex arrays whose real and imaginary parts are contiguous in storage.

The ith elemeent of this Z1
o put 
 public void put(int i,
                 Z z)
Sets the ith element of a Z1 to a Z.

Parameters:
i - an integer
z - a Z
Returns:
resets the ith element of this Z1 to z
o put 
 public void put(int i,
                 double real,
                 double imag)
Sets the real and imaginary parts of the ith element of a Z1.

Parameters:
i - an integer
real - a double
imag - a double
Returns:
resets the ith component of this Z1 to real + i*imag
o Times 
 public void Times(int i,
                   Z z)
