* 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. | * 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).

* Write self-tests for a function [[Files missing tests|missing test]]; see also [[Projects#Tests]]. | * Write self-tests for a single function. For core Octave see [[Files missing tests|missing test]]; see also [[Projects#Tests]]. | ||
* Use non-empty identifiers in all warnings and errors issued by Octave; see {{bug|39439}}, {{bug|39434}}, {{bug|37559}}, {{bug|36861}}. You may tackle as many or as few IDs as you have time for. As it is a widespread issue, finding occurrences in the source code should give you valuable knowledge about the way Octave files are organized. | * Use non-empty identifiers in all warnings and errors issued by Octave; see {{bug|39439}}, {{bug|39434}}, {{bug|37559}}, {{bug|36861}}.
