This is a Scala library of units of measurement featuring the International System of Units (SI).

The main types defined are Quantity and Unit.

This is a Scala library of graphics utilities. It is focused on simple drawing of shapes and functions without the need of instructing the graphics system by a dozen or so settings before a simple picture is shown. It is not meant to program graphical user interfaces with buttons, menus and so on.

This is a Scala library of essential algorithms.

It starts with Scala implementations of some algorithms from the book Algorithms 4 by Robert Sedgewick and Kevin Wayne [1]. Further adaptations from this book will be added from time to time. Other algorithms may go into this library as well.

This is a Scala library of programming utilities. It is not intended to comprise a systematic collection but contains some tools that happen to be useful for myself and may be of interest for others.

This is a Java library of some tools that happened to be useful in a predictive-analytics environment. In fact, most of them are not specific to this area and might be of general interest.

There is also a Scala interface for some sub modules, currently for pa-toolbox-linalg and pa-toolbox-plotting. It simplifies the use of these modules with Scala in general and with my LinAlg Scala Library in particular.
