[Scilab-users] Different results inside a function and in the console

[Izabela Wójcik-Grząba]

Thank you Federico. I did some tests to check what can be wrong but I 
failed and till this moment I don't know what was wrong. Fortunately I 
did some reorganisation in my code and now it works fine. Sorry for 
bothering but after many failures in tests I was really frustrated.

Have a nice day,
Iza
