[Scilab-users] strange error with "rat"

[philippe]

Hi to all,


I use rat to do integer simplifications in vectors (if possible).  I use
it like this

-->[n,d]=rat(2/14)
 d  =

    7.
 n  =

    1.

but I have a strnage error when rat is called  from another (very
complex) function :


***********************************************

-->[D,P,txt]=diagonalisation(A,'txt', variables, 'M')

 !--error 246
Fonction non définie pour le type d'argument donné,
  Vérifier les arguments ou définir la fonction %s_rat pour la surcharge.

at line      83 of function diagonalisation called by :
********************************************************

I've checked that the argument of rat is a constant (it's -1/2), but I
can't reproduce the bug out of this context!?!?

Does anyone have any idea of what could have happened ?
