*Improve logm, and sqrtm (see this thread: http://octave.1599824.n4.nabble.com/matrix-functions-td3137935.html)
*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.

*Make the website prettier. Maybe a new design, maybe a more "corporate" design (if we're heading down the "paid support for Octave" path.
* Make the Octave website/[[Project Infrastructure]] easier to maintain.
 
** FusionForge's "Submit a Snippet" and "Create A Package" would seem 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 software.  


*Move [https://octave.sourceforge.io/ Octave-Forge] to [https://savannah.gnu.org/projects/octave/ Savannah] so everything is hosted in the same place.
* Make it easier for newcomers to contribute.

'''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 binary packaging ==
== Improve macOS binary packaging ==


We would like to be able to easily generate binary packages for Mac OS X. 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 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]?).
