Hi Claus,
For small dialogs to ask inputs, use *x_mdialog* function (
http://help.scilab.org/docs/5.5.0/fr_FR/x_mdialog.html )
function result = compute_voltage()
txt = ['Power (Watt)';'Impedance (ohm)'];
values = *x_mdialog*('System values',txt,['100';'8'])
if values <> [] then
w = values(1);
o = values(2);
w = eval(w);
o = eval(o);
if typeof(w) <> "constant" | int(w) <> w | typeof(o) <> "constant" |
int(o) <> o then
error("bad value, integer values expected");
end
result = sqrt(w * o);
else
result = [];
end
endfunction
voltage = compute_voltage()
