Better. Stronger. Unified

Release 1.6.0 - Grand Unified Yacas

True to it's codename, the release finally brings together the CAS engine library, text console, graphical interface and yacas kernel for Jupyter Notebook. And adds a complete in-browser CAS for a good measure.

Yagy, the Yet Another GUI for Yacas, and yacas_kernel, the yacas kernel for Jupyter Notebook, previously developed as independent packages, have been integrated into the main yacas codebase. Oh, and one more thing – we cross-compiled yacas to JavaScript and slapped GUI from yagy on top, getting a fully yacas-compatible in-browser Computer Algebra System.

Hence, starting from this release, yacas provides:

  • native (C++)
    • CAS engine library (libyacas),
    • text console (yacas),
    • Graphical User Interface (yacas-gui),
    • kernel for Jupyter Notebook (yacas-kernel)
  • platform-independent (Java)
    • CAS engine and text console (jyacas)
  • in-browser (JavaScript generated from C++ sources)
    • CAS engine with Graphical User Interface (yacas-online)

Downloads

You can download yacas from the Downloads page. Please note that not all binary packages may have been uploaded yet.
