=== Interval package ===

The [[Interval_package|interval package]] provides several arithmetic functions with accurate and guaranteed error bounds. Its development started in the end of 2014 and there is some fundamental functionality left to be implemented. See the [http://octave.sourceforge.net/interval/overview.html list of functions], basically any missing numeric Octave function could be implemented as an interval extension in the package. ~~ If the student has previous ~~Potential projects:* Implement missing algorithms (as m-files)—difficulty and whether knowledge in interval analysisis required depends on the particular function. Of course, ~~it is also possible to implement ~~you may use papers which present such ~~missing ~~algorithms.* Improve existing algorithms (~~as m~~support more options for plotting, support more options for optimizers, increase accuracy, …)* Make the package support N-dimensional arrays, this requires less knowledge of interval arithmetic but can be a rather exhaustive job since it affects most function files~~) or improve ~~in the ~~existing algorithms. ~~package

'''Required skills''': m-file scripting, basic knowledge of computer arithmetics (especially floating-point computations), interval analysis (depending on the functions to implement)
