function lottonumbers = draw_lottonumbers(draws, balls,rows)
% A function that draws 'draws' random integers without replacement 
between 1 and
% 'balls', i.e. a random lotto sequence
% INPUT PARAMETERS
%   draws: # of balls drawn (in norwegian lotto this is 7)
%   balls: # of balls, i.e. # of possible numbers (in norwegian 
lotto this is 34)
%   rows:  # of lottorows (in norwegian lotto this is normally 10)
% OUTPUT PARAMETERS
%   lottonumbers: a matrix with 'rows' rows, where the rows are the
%              lotto-combinations you play
lottonumbers = zeros(rows,draws);
for i=1:rows
       temp_combination = randsample(balls,draws,'false');
          % draw 'draws' integers between 1 and 'balls'
       lottonumbers(i,:) = sort(temp_combination);
          % sort the drawn lottosequence in ascending order
end
using function above:
function thrtyfoinrow=drawlotto(v)
thrtyfoinrow=0;
draw_lottonumbers(7,34,v)
winner=rand(1,7);
winner=ceil(winner);
for i=1:v
      if winner==lottonumbers(i,:)
          for j=1:v
            if winner(j)==34
                thrtyfoinrow=thrtyfoinrow+1;
            end
          end
      end
end
