I would like to delete the two packages from science.
FreeMat is a software similar to Octave or Matlab. It has seen no upstream development for 4 years and no longer builds on TW and Leap 15.
qtoctave is a gui frontend for Octave and has seen no upstream development for 6 years.
As Octave has a gained a native GUI since I think there is no reason to keep the other two packages. If nobody protests, I will delete the two packages on next Monday, 2018-07-09.
