* Completeness

** All required functions from IEEE Std 1788-2015, IEEE standard for interval arithmetic, are implemented. The standard was approved on June 11, 2015. It will remain active for ten years.

** ~~Planned: more solvers~~~~*** <code>fsolve</code>~~In addition there are functions for interval matrix arithmetic,~~*** ~~plotting and ~~possibly <code>roots</code>~~~~*** Algorithms can be migrated from the C-XSC Toolbox (C++ code) from [http://www2.math.uni-wuppertal.de/wrswt/xsc/cxsc_new.html] (see nlinsys.cpp, and cpzero~~solvers.~~cpp respectively).~~~~** Planned: Improvement of the user documentation~~~~*** Explain more interval arithmetic concepts with examples from the package~~~~** Planned: Interval version of <code>interp1</code>~~

* Quality

** Includes tests for all functions, many tests for basic functions

** No known bugs. The package is quite new and still has a small user base, so there might be hidden bugs. Also some advanced functions will always need more testing.

* Portability

** Runs in GNU Octave 3.8.2 and 4.0.0

** Known to run under GNU/Linux, Microsoft Windows, Mac OS X and FreeBSD

* Possible TODOs

** To be considered in the future: Algorithms can be migrated from the C-XSC Toolbox (C++ code) from [http://www2.math.uni-wuppertal.de/wrswt/xsc/cxsc_new.html] (nlinsys.cpp and cpzero.cpp), however these would need gradient arithmetic and complex arithmetic.

** Interval version of <code>interp1</code>
