Changelog

  • This version is the same as suspended 0.3.0 except bug-fixes for French translation
  • Following changes are related to 0.2.1
  • Added:
  • more numerically stable method (QR decomposition)
  • OOo's LINEST() function with force Y(0,F) option for linear case
  • translation functions
  • French and Polish locale

Known problems

  • "QR decomposition" stops working in case of [number of points] = [max. deg. + 1]
    This is a problem with "vect_norm" function. It doesn't affect another cases.
