function x = realize(range)

% REALIZE .....	Generates all realizations (sample functions) of the random
%		process X(t) =  cos(2*pi*1000*t + THETA).
%
%	X = REALIZE([a1,a2,...]) uses the values {a1,a2,...} to generate 
%		discrete valued uniformly distributed random variable THETA.
%		For example, if the input parameter is [0 pi/2 pi], then
%		THETA takes the values 0, pi/2, pi with equal probability.
%
%     		X(n,t) represents the nth sample function at time t = 0,1,.. 
%		(in msec.),  Each realization consists of '1000' samples. 
%		Each period has 100 samples.
