Add reference to Pairwise Summation
*Improve logm, and sqrtm (see this thread: http://octave.1599824.n4.nabble.com/matrix-functions-td3137935.html)
 
*Use pairwise addition in sum() to mitigate against numerical errors without substantial performance penalty (https://en.wikipedia.org/wiki/Pairwise_summation).
 
*Review implementing algorithm in this 2009 paper (https://epubs.siam.org/doi/pdf/10.1137/080738490) for xsum (sum with extra accuracy). The existing implementation uses a 2005 paper.
*Improve complex mapper functions. See W. Kahan, ``Branch Cuts for Complex Elementary Functions, or Much Ado About Nothing's Sign Bit (in The State of the Art in Numerical Analysis, eds. Iserles and Powell, Clarendon Press, Oxford, 1987) for explicit trigonometric formulae.
=Marketing and Community=
*Make the Octave website prettier. Maybe a new design, maybe a more "corporate" design (if we're heading down the "paid support for Octave" path. ** FusionForge's "Submit a Snippet" and "Create A Package" would seem /[[Project Infrastructure]] easier to be directly usable for Agora's "Post a Snippet" and "Share your Code", respectively: https://alioth.debian.org/snippet/. It is FLOSS.** ScipyCentral, http://scipy-central.org/ has all the features we need and is also free softwaremaintain.
*Move [https://octave.sourceforge.io/ Octave-Forge] Make it easier for newcomers to [https://savannah.gnu.org/projects/octave/ Savannah] so everything is hosted in the same placecontribute.
*For marketing ideas, see the [httphttps://openoffice.apache.org/orientation/intro-marketing.html Apache Open Office Introduction to Marketing]
* Help design a user or a developer survey [httphttps://www.openoffice.org/marketing/ooocon2006/presentations/wednesday_c10.pdfdeveloper survey]
* Help prepare and deliver presentations about Octave at colleges and universities.

== Improve Windows binary packaging ==
'''Skills Required''': Knowledge of GNU build systems, Makefiles, configure files, chasing library dependencies, how to use a compiler. No m-scripting or C++ necessary, beyond understanding [http://david.rothlis.net/c/compilation_model/ the C++ compilation model].
== Improve Mac OS X macOS binary packaging ==
We would like to be able to easily generate binary packages for Mac OS XmacOS. Right now, it's difficult and tedious to do so. Most OS X users install Octave using one of the source-based package managers such as Homebrew or MacPorts. Any way to help us build a binary package would be appreciated. Required knowledge is understanding how building binaries in Mac OS X macOS works. Our current approach to building binaries for Windows is to cross-compile from a GNU system using [http://mxe.cc/ MXE], something similar may be possible for OS X ([http://lilypond.org/gub/ GUB]?).
'''Skills Required''': Knowledge of GNU build systems, Makefiles, configure files, chasing library dependencies, how to use a compiler. If you choose to work on GUB, Python will be required. No m-scripting or C++ necessary, beyond understanding [http://david.rothlis.net/c/compilation_model/ the C++ compilation model].
