%   This is a sample m-file for projects in MA 486/586 (Statistics)
%
%   This program simulates n=100 values of a normal random variable,
%   then finds their sample mean, and then repeats this simple
%   experiment m=10 times. In the end it prints (on the screen) 
%   the computed means (all m=10 values).
%
%   To use it, type "means" in the MATLAB window, the program
%   will run and you will see 10 computed sample means on the screen

%   here is a loop running over m times

for i=1:m            %  starts the loop
    X=randn(n,1);    %  generate a random vector of size n times 1
    u=mean(X);       %  finds the mean value of the sample X
    M(i)=u;          %  saves the mean value to the current position of M
end                  %  ends the loop

M                    %  prints the components of the vector M
