This is rather getting the variable name from the variable handle

AFAIK, this is possible only if s is the handle of a Scilab function (so called "macro"), i.e. a function written in Scilab language and compiled.

Example with the existing sind() function:
t = macr2tree(sind); t.name
// It works even with aliases:
s = sind;  // with no (): we copy the handle into s
s(45)
t = macr2tree(s); t.name

-->t = macr2tree(sind); t.name
 ans  =
 sind   
 
-->// It works even with aliases:
-->s = sind; // with no (): we copy the handle into s
-->s(45)
 ans  =
    0.7071068  
-->t = macr2tree(s); t.name
 ans  =
 s

I do not clearly understand what is done there. No results are displayed..
I don't know any equivalence of inputname() in Scilab.
