% Lotto Program
% This is the lotto program where one can select m numbers from xlow to
% xhigh.
clc
xlow=1;
xhigh=53;
m=6;
% using the random number generator rand to get the lotto numbers.  rand
% generates numbers between 0 and 1.  So we multiply that by xhigh-xlow+1
% and shift it by xlow and then floor it to get the integer part.  1 is
% added as rand will always be strictly >0 and strictly <1.
for i=1:m
    lottonum(i)=floor(xlow+rand*(xhigh-xlow+1));
end
