[CRETE Denis]

Hello,
if Z is the COLUMN vector of the complex numbers to be plotted on the (x,y) plane, then
plot2d(real(Z), imag(Z));
 should draw the path having k-th vertex at Z(k). To draw a circle of radius R and enter C, it is possible to define Z as follows:
Z=C+R*exp(%i*2*%pi*0:0.01:1);
Hope this helps
Denis

A two dimensional complex plane is geometrically identical to a
conventional Cartesian plane, with the y-axis relabeled "i".  That is, your
unit circle is defined by:

(REAL coefficient)^2 + (IMAGINARY coefficient)^2 = 1

which gives the unit circle centered on the origin.  For a circle centered
at point (x1+y1i), you would use:

(REAL coefficient - x1)^2 +(IMAGINARY coefficient - y1)^2 = 1

You would take a similar approach with your transfer function.

Hi !! First of all thank you very much for your reply !
Could you guide me on how to write it in scilab so that i can get the plot ? 
Ive been trying for very long but cant seem to be able to write it the way
scilab would accept..
Thanks once again for the reply :)
