I'm not completely sure, but I think this is not possible since what is
passed to the function isn't a variable but the value contained in the
variable. The name is lost in the process.
An alternative way (but I don't know if this would be acceptable for
you) is that the function had as its argument a variable name (hence, a
string), so your x would be "xNum", instead of 123. Then you could use
evstr() to get the value of the variable to proceed with the processing.

Hi Scilab friends,
Given a numeric variable like xNum as an input argument of a function
call, how can I produce the variable name string "xNum" within the
function?
Example:
function [name,y]=foo(x)
name=???
y=x^2
endfunction
xNum=123.
[name,y]=foo(xNum)
The result for name should be the string "xNum"
Regards
Jens
