[Scilab-users] Get back the name of a function given as argument

[Pierre Vuillemin]

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 ?

Pierre
