New data types for GNU Octave

The datatypes package is an extension for GNU Octave, which provides a set of new data classes for tabular, categorical, and time-related data. These new data types are essential to statistical and time-series analysis and aim to facilitate advanced data analysis workflows in GNU Octave. The vision behind datatypes is provide robust and well-tested implementations of table, timetable, and geotable objects, which in addition to their MATLAB-compatible features will also provide integration and data exchange functionality with other widely used data formats, thus enhancing interoperability with the GNU Octave ecosystem. Besides the tabular classes, the datatypes package already supports classes for calenderDuration, categorical, datetime, duration, and string arrays and it is within the scope of this project to extend its support to timeseries arrays and dictionary objects. This project aims to the complete the missing features of the datatypes package along with the development of comprehensive documentation and testing suite in order to provide production-ready data types for the GNU Octave language.
