== Get file info when generate_html fails or warns==
 
Since generate_html gives errors about the random files generated, it is useless when debugging help text. The following command shows the first few lines of the files created by generate_html.
 
 
 
<pre> f_old=/tmp/$(ls -1 -t /tmp | head -1);while true; do f=/tmp/$(ls -1 -t /tmp | head -1); if [ "$f" != "$f_old" ]; then echo $f; grep '@def' --include="*octave-help*" $f; f_old=$f; fi; done</pre>
 
 
 
run this in a different terminal before using generate_html
 
is not ideal,but it does the trick
 
 
 
== Make options ==
 
Some options to pass to make when compiling from source
 
 
 
# <pre> DOC_TARGETS= </pre> avoids building the PDF but still builds function helps.
 
# <pre> --disable-atomic-refcount</pre> improves performance when building CLI only.
 
 
 
== Getting help from CLI==
 
# know the function --> <code>help function_name</code> or <code>help function_name</code>.
 
# Know what to do but not the function name --> <code>lookfor what_to_do</code>.
 
# Can't remember the fullname of a function (or have a guess) --> partial_name_of_function then press <TAB-key> twice
 
# Did it once but can't remeber --> <Ctrl>+<R> to search the history.

== Geometry package ==

=== extend sub2ind and ind2sub ===
* Add nmf_bpas and nmf-pg  to linear-algebra <span style="color: green;">✔</span>

** Add it to linear-algebra and create nnmf.m compatible with MATLAB calling all the methods.
 
 
 
== GPML ==
 
* Asked for a GPLv3 version of [http://www.gaussianprocess.org/gpml/code/matlab/doc/index.html GPML]. They answer but license is FreeBSD. A new version is comming out in June 2012, so I will wait to start the port.<span style="color: green;">✔</span>
 
* Create [https://bitbucket.org/KaKiLa/gpml repository] to keep scripts to package it for OF. <span style="color: green;">✔</span>
 
 
 
== make output format a valid input format ==
 
An output format that prints valid input commands, so one can copy and re-execute the code.
 
From IRC
 
 
 
(04:57:05 PM) jwe: It might not be too hard to implement what you want.  There is a flag in the pr-output functions for pr_as_read_format and many (but probably not all) of the types that are printed there do something with that.  And it is not hooked in to the format function, so you can't enable it.
 
 
 
(04:57:31 PM) jwe: pr-output.cc and pr_as_read_syntax
 
 
 
== extend sub2ind and ind2sub ==
 
 
We are extending sub2ind and ind2sub to work with triangular matrices. Currently private functions of {{Forge|mechanics}}.

A string argument triggers the behavior. The string argument can be "triu" or "tril". After this str argument we accept an extra scalar value indicating that the triangular matrix is off diagonal (as in tril and triu).
