Hi,

Could you please register me as an Octave-Forge developer?
I have some code that was written in Matlab, and I've been trying to
make it Octave compatible. Part of it uses the fminbnd function, however
the Octave-Forge function is not as fast as the Matlab one because it
does not use parabolic interpolation. I plan on integrating the
parabolic interpolation in the current fminbnd code and contribute it.

Thanks,

Florent

Florent,

We have no problems giving out write access to octave-forge, but prefer
to see a code sample on the list first. This is not really for code
review but rather to keep the number of inactive accounts on
octave-forge down.. Can you send your changes here first and Soren or I
will immediately give you write access.

Cheers
David

Hi,

Sorry for the delay... At the moment, I'm not finished with the inverse
parabolic implementation. However, I can submit a little fix that
prevents the function to break if the upper bound of the search interval
is the same as the upper bound (attached file). This makes the function
behave just like its Matlab counterpart.

Cheers,

Florent

Florent,

Could you send your changes as a patch rather than the complete code..
Sending the complete function makes it very difficult to see what in
fact you have altered. Use "svn diff" to create this if you are using
the SVN tree, or just "diff -u" with a local of the original function if
you aren't.

Also I don't think we've added an account for you, so when you send the
code as a patch, please supply your sourceforge username.

Regards
David

Hi David,

My Sourceforge account login is "floflooo".
Attached is the diff file for the Octave-Forge function. As I said, this
one is trivial, a one-liner.
May I suggest that someone updates the webpage "Contributing Code to the
Gnu Octave Repository" http://octave.sourceforge.net/developers.html 
with all the information that you gave me. I am sure you would be glad
to avoid repeating the same thing over and over again.
Thanks,

Florent

Added, so please commit your patch..

The webpages themselves are also built from the SVN. See the doc/htdocs
directory and the admin/template.ndev file, and propose a patch.

Hi,

I was given access to the SVN repository yesterday but have trouble
using it. In particular, I cannot seem to commit.
I checked out the repository without problem:
> floflooo@localhost:~$ svn co
> https://octave.svn.sourceforge.net/svnroot/octave/trunk/octave-forge
Then changed some code in my working copy of the repository.
Then I try to commit the changes:

> floflooo@localhost:~/octave-forge$ svn commit -m ""
> Authentication realm: <https://octave.svn.sourceforge.net:443>
> SourceForge Subversion area
> Password for 'floflooo':

When I logged in to Sourceforge yesterday, I had to update my password.
I use my Sourceforge username and updated password and am able to log in
to Sourceforge. Also, I can see that I am affiliated to the Octave
Sourceforge project.

How can I troubleshoot this problem?
Thanks,

Florent

It seems ok from my end, can you try again and see if its just a
question of the password propagating to the SVN server. You probably
also should try and upload your SSH key to

https://sourceforge.net/account/editsshkeys.php

then after a few hours try to ssh to floflooo@... and see if
you can, though I'm not sure this will help with the SVN access though
will confirm that your password is correct.

I uploaded my ssh key. Initially it didn't solve my problem. I retried
several times today, and now finally it worked and I could commit.
Thanks for your assistance David,
Florent
