<font face="Courier New">No. Internally, input arguments are passed
as references to the true object. There is no copy unless an input
argument is modified in the function (in that case a copy with
local scope only). </font><br>

<font face="Courier New">Yes, before the first line of the function
body the original object has the name of the argument, although
both names refer to the same object.</font><br>

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.<br>

Hi Scilab friends, <br>
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? <br>
<br>
Example: <br>
<br>
function [name,y]=foo(x) <br>
name=??? <br>
y=x^2 <br>
endfunction <br>
<br>
xNum=123. <br>
[name,y]=foo(xNum) <br>
The result for name should be the string "xNum" <br>
<br>
Regards <br>
Jens <br>
