how to use handle to chane figure size

[paul.carrico at free.fr]

All,

Ahhhhhhhhhhhhhh ... i'm spending (and wasting) a lot of time to understand how to use handles to increase the figure size !!!

basically I used until now :
clf(0)
xtitle("Resultat TRACTION","epsilon [-]","sigma [MPa]")
plot(TRACTION(:,3),TRACTION(:,4))
xs2jpg(0,'essais_traction.jpg');

and after reading the 'help figure_properties' I try several things by I failed each time ..

So can somebody share a part of a code to change this *$+&&%%%:-((((  size ?

Thanks in advance

Paul
