Cellular Traffic Calculation

by

 

A GUI that will calculate the traffic in a given area and draw suggested locations for the cells.

H=circle(center,radius,NOP,style)
function H=circle(center,radius,NOP,style)
%---------------------------------------------------------------------------------------------
% H=CIRCLE(CENTER,RADIUS,NOP,STYLE)
% This routine draws a circle with center defined as
% a vector CENTER, radius as a scaler RADIS. NOP is 
% the number of points on the circle. As to STYLE,
% use it the same way as you use the rountine PLOT.
% Since the handle of the object is returned, you
% use routine SET to get the best result.
%
%   Usage Examples,
%
%   circle([1,3],3,1000,':'); 
%   circle([2,4],2,1000,'--');
