Update of bug #62682 (project octave):

              Item Group:           Documentation => Unexpected Error or
Warning
                  Status:                    None => Fixed

Follow-up Comment #14:

The warning about inline functions is intended for programmers so they
understand that they should update their m-files to use anonymous functions. 
In this case, ezplot.m is a core Octave function and it is knowingly using
inline() to accomplish a specific task.  I don't think it needs to warn about
it.  For reference, the symvars.m function specifically turns off the warning
before using inline in a known way to accomplish a known goal.


function vars = symvar (str)

  warning ("off", "Octave:legacy-function", "local");  # using inline below.
  vars = argnames (inline (str));
  ## Correct for auto-generated 'x' variable when no symvar was found.
  if (numel (vars) == 1 && strcmp (vars{1}, "x") && ! any (str == "x"))
    vars = {};
  endif

endfunction


Using grep, there are two functions---__ezplot__.m and fplot.m---which make
use of inline().  I temporarily disabled the warnings in this changeset:
http://hg.savannah.gnu.org/hgweb/octave/rev/18b8f73595e0.

For fplot, Matlab issues a warning when a string is used as input which notes
that this syntax will be removed in a future release and then recommends using
anonymous functions.  Octave could do the same thing as well.

Marking bug as Fixed and closing report.
