%  This m-file runs the noise simulation models:

%   Discrete_Digital_Noise                           
%   Discrete_Digital_Noise1                          
%   Discrete_Digital_Noise2                            
%   Discrete_Digital_Noise3
% 
%  using the MATLAB sim command with tic and toc before and after the
%  simulation to evaluate the total time taken to exceute the models.  The
%  resulting simulation times are stored as t0,t1 t2 and t3.  

for j =1:10
    for i = 0:3
        %  Create a string that will evaluated to:
        %        tic; sim('test"i"); t"i"=toc
        %  Where "i" evaluates to 0,1,2, or 3 from the command num2str(i)
        %  (this command converts the floating pt. number i to a string)
        str = ['tic; sim(''test' num2str(i) '''); t' num2str(i) '(' num2str(j) ')=toc;'];
        eval(str)
