My bad, I've just realised that
- this routine will actually give the name of the last copy of the
function (in case of multiple imbricated function calls),
- besides, a simpler solution consists in using the name of the local
copy of the function.
deff('y = fun(x)','y = x^2');
deff('y = f(x)','y = x');
deff('minimize(f)','disp(evstr(''f(2)''))');
minimize(f) // displays 2
minimize(fun) // displays 4

Hi Samuel,
Thank you for the answer. I have finally came up with this routine :
function funName = sopi_retrieveFunName(f)
varList = who_user(%f);
for i = 2:size(varList,1) // "f" is the local copy of the function
and is the first one in the varList, it must be discarded
varName = varList(i);
execstr("var = "+varName);
if var == f then
funName = varName;
break;
end
end
endfunction
It retrieves the name of the function given as argument by comparing
it to the user's variables. It (very) far from being elegant, but it
seems to work.
Will there be a better way to achieve that with Scilab 6 ?

Hi all,
I am building some optimisation tools, and in this context, I was
wondering if it was possible to get back the name of a function given
as argument of another function.
More specifically, consider the function 'fun' defined as
deff('[f,g] = fun(x)','f = x^2;g = 2*x');
and an optimisation routine "minimize" which first argument is a
function.
Is there a way to get back the name of the function "fun" when
calling "minimize(fun)" ?
I am afraid that, with 5.5.2, you have to use something like
minimize("thefun") instead, with
function argout = minimize(fun,...)
execstr("fun="+fun);
...
endfunction
Samuel
