  Nope! It's the contrary. 

  QHull is for Convex Hull (of a set of points) : it's computational
geometry.

  Symbolic toolbox. From the description of the Debian package:
GiNaC (which stands for "GiNaC is Not a CAS (Computer Algebra
System)") is a library for doing symbolic (i.e. non-numeric)
computation directly in the C++ programming language.

# 3. atlas = automatically tuned linear algebra subgroups. No longer needed in

  Save data in .hdf format, a "universal" format for numerical data,
iigc.
