plotting question

[Gergely CZUCZY]

hello

i'd like to do a plot, and it works fine for the
first running of the script. after the first run,
i close the plot window and whenever i try to execute
the script again, no plot window appears. however, also
no errors i got from octave.

what am i doing wrong? the scriptfile si the following:


--- BEGIN myscript.m ---
sol=-10:0.1:10;
tax=0.25;
basesavings=5;
moralexp=0.7;
salar=0;
savings=0;
soleff=0;
newsav=0;

function salary = sol_salary(sol)
  salary =  9.2*(atan(sol/3)/(pi/2)).^3+15;
endfunction

function [soleff, newsavings] = expsav_solsav(expenditures, savings)
  sp_offset=-20;
  sp_scale=10;
  sp_b=0.1;
  sp_middle=16.7;
  spending = atan(((savings.*expenditures)+sp_offset)*sp_b)*sp_scale+sp_middle;
  newsavings = savings - spending;

  sol_offset=-12;
  sol_scale=9.5;
  sol_b=.2;
  sol_middle=-2.412;
  soleff = atan((spending+sol_offset)*sol_b)*sol_scale+sol_middle;
endfunction

salary = sol_salary(sol);
savings = salary+basesavings;
[soleff,newsav] = expsav_solsav(moralexp, savings);

subplot(1,2,1);
plot(sol, salary, '-;sol->salary;');
subplot(1,2,2);
plot(savings, soleff, '-;soleff;');
hold on;
plot(savings, newsav, '-;newsav;');
hold off;
--- END myscript.m ---

Bye,
