* {{bug|33935}} - demo function humps is not defined
* {{bug|48151}} - pkg update - error if packages are specified

== Missing functions ==


* there is a list of missing functions for the [[image package|image]], [[mapping package|mapping]], [[Optimization package|optimization]], and [[Signal package|signal]] packages.
* There are lists of missing functions for [[:Category:Missing functions|several packages]].
** It would help to group the several missing functions in the [[image package]], as per [http://www.mathworks.com/help/images/functionlist.html] (similar to what was done in the [[signal package]] wiki page); please keep the original alphabetical list intact.

* openfig/savefig functions

** These should be particularly easy additions as they are really just a wrapper on top of hgload/hgsave.
** These should be particularly easy additions as they are really just a wrapper on top of hgload/hgsave.
* integral/integral2/integral3 functions
 
** These are basically renamed versions of quad/dblquad/triplequad.  It shouldn't be hard to make new functions which use the new integral naming system from Matlab.  See also {{bug|42037}}.
== Function Compatibility ==
*** one note, the new integral functions do change usage slightly from quad. E.g., quad and quadv were the only integrators that didn't require vectorized functions (as opposed to quadgk, quadcc, etc.).  Also, passing parameters to integrating functions is more uniform than the different quad functions, where some (such as quad) does not include parameter passing. Compatibility should be checked for any wrapper made.
A number of functions are implemented, but may have known incompatibilities or only partially handled option sets, etc.
* integral - currently cannot handle all optional inputs, see see {{bug|42037}}

* C++ cleanup of core after the switch to exceptions (late 2015). There are about 100 instances to clean up and each one takes less than 5 minutes.  See [[Invert if/else/error]].

* Use "units.h" from [http://www.gnu.org/software/units/ GNU units] in [http://octave.sourceforge.net/miscellaneous/function/units.html function units] (from the Octave-Forge [http://octave.sourceforge.net/miscellaneous/ miscellaneous package]) rather than making a system call and parsing its output (and having to handle multiple versions of it). This change will make it much more robust. It likely will alleviate the requirement of having [http://www.gnu.org/software/units/ GNU units] installed in the system separately by the user. This requires knowledge of C (units is written on C) and C++ to write its Octave interface. It can be very easy if the units.h truly allows to be used as library or maybe impossible if it does not. This has not been investigated yet.
