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 38 of function vector2int called by :
at line 95 of function matrix2noyau called by :
at line 61 of function eigenvector called by :
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 ?
When the %s_ overload is called, it is often due to some unsupported
complex values (even with null imaginary parts: only the encoding
matters).
So, you may check before calling rat() that its input argument is not
of complex type , with isreal(x).
