%INPUTNAME Input argument name.
%   Inside the body of a user-defined function, INPUTNAME(ARGNO) returns
%   the workspace variable name corresponding to the argument number
%   ARGNO.  If the input has no name (for example when it is the
%   result of a calculation), then INPUTNAME returns the empty string.
%
%   Example: Suppose the function myfun is defined as:
%     function y = myfun(a,b)
%     disp(sprintf('My first input is "%s".',inputname(1)))
%   then
%     x = 5; myfun(x,5)
%   produces
%     My first input is "x".
