%  Script file: test_runstats.m 
% 
%  Purpose:  
%    To read in an input data set andn calculate the  
%    running statistics on the data set as the values  
%    are read in.  The running stats will be written 
%    to the Command window.

% Define variables: 
%   array  -- Input data array 
%   ave    -- Running average 
%   std    -- Running standard deviation 
%   ii     -- Index variable 
%   nvals  -- Number of input values 
%   std    -- Running standard deviation 
 
% First reset running sums 
[ave std] = runstats('reset'); 
 
% Prompt for the number of values in the data set 
nvals = input('Enter number of values in data set:  '); 
 
% Get input values 
for ii = 1:nvals 
 
   % Prompt for next value 
   string = ['Enter value ' int2str(ii) ':  ']; 
   x = input(string); 
    
   % Get running statistics 
   [ave std] = runstats(x); 
    
   % Display running statistics 
   fprintf('Average = %8.4f; Std dev = %8.4f\n',ave, std);
