Hello Philippe,
The overloading mechanism is not systematic. It is implemented (or not)
function per function.
It is currently proposed for some of them, but not all of them.
If you need it for double(), you shall post a wish on Bugzilla.
Best regards
Samuel
PS: for instance, iconvert(p,0) makes the same as double(), and is
overloadable:
--> iconvert(%z,0)
in builtin iconvert
Function not defined for given argument type(s),
check arguments or define function %p_iconvert for overloading.

Hi,
I want to overload some usual scilab functions, I made it for abs and
sign but strangely it doesn't work for double ! Let's take an example ,
I want to extend sign and double for polynomials :
--> X=poly(0,"x"); // a polynomial
--> sign(X)
dans la fonction native sign
Fonction non définie pour les types fournis.
vérifier les arguments ou définir la fonction %p_sign pour la surcharge.
--> double(X)
double : Types erronés des arguments d'entrée : entiers, booléens ou
réels attendus.
so I define overloading for the two functions and "p" type :
function y=%p_sign(x)
y="OK"
endfunction
function y=%p_double(x)
y="OK"
endfunction
Now I can call sign on a polynomial, but this doesn't work for double
--> sign(X)
ans =
OK
--> double(X)
double : Types erronés des arguments d'entrée : entiers, booléens ou
réels attendus.
How can I do this for double ? If not why this doesn't work ? Both sign
and double are "fptr" type , I thought that scilab-6 doesn't make
difference between function and fptr any more .
Philippe
