the problem in this program is that executed only one then closed

i need to re excited until push close button what function that can do this???

can i use while loop or something!!!!!!1

   'ymax',
   'xmin',

options.Resize='on';

value = {'','3','-20','20','-20','20'};

answer = inputdlg(prompt, dlgtitle, no, value, options);
  N =str2double(answer(1,:));

dis =inputdlg( cellstr( num2str((1:N).', 'distance number %d') ),dlgtitle,no );
% answer_str = char(answer);
h=((xmax-xmin)/2)+xmin;

for i=1:N-1
    distance(i)=str2double (dis(i,:))/2;
    x(i)=h-distance(i);
    x(N)=h;

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
end
for i=1:N-1
 x(i+N)=h+distance(N-i);   
end

for i=2:N-1
    y(i)=y(i-1)+step;
end
for i=1:N-1
    y(2*N-i)=y(i);

end;
w=2*N-1;
j=[x(N-1) x(N) x(N+1:w)];
b=[y(1) y(N) y(N+1:w)];
 patch(j ,b,'y');
