List functions defined from within current scope

[paul]

As recently as 2008, Octave 3.0.2's "who" function accepted a "-functions"
option for listing user-defined functions:

http://www.network-theory.co.uk/docs/octave3/octave_66.html

I don't that command & option serves my aim of listing only functions that were
defined from within the current scope, as the option is no longer available in
Octave 3.6.2 and I can't test it.

Is there another way to list user-defined functions and/or functions defined
from within the current scope?

functions defined in the command line are pretty much invisible.
octave:1> function f(); disp(1); end
octave:2> who
octave:3> whos

I wouldn't know why the function is not shown. Maybe it is just
something that got lost in the way?

I suppose all user-defined functions should be present in the current workspace as function handles. If so, then "whos" returns structure with one of the fields "class". Comparing class field to string 'function_handle' should return the logical index matrix. It could look some like this:
wrks = whos;
mask = strcmp({wrks.class},'function_handle');
fun_names = wrks(mask).name

Doesn't work for the above example (i.e. comand line: function f(), disp(1); end), I have read after posting. I probably offered the solution you are not looking for.

That doesn't seem to work here.
Do you have a working example?

I didn't find any possibility to display functions created by function keyword, but if you know which functions should be created and you just want to check if they were, you can use exist('funname') command. In case of function defined from the command line it returns 103 and for function within m-file, invisible from command line otherwise, it returns 2 if checked from the current scope, e.g. during debug mode.
If you are producing unknown number of functions with unknown names than I'm not able to help.
