Thank you for all who point to the vector/matrix capabilities in Ruby.
But for now, even SciRuby says that "Ruby has for some time had no
equivalent to the beautifully constructed NumPy, SciPy, and matplotlib
libraries for Python."

For vector, NMatrix is in second alpha stage.  Depending on the OP's
need, probably NArray will be enough.

But what is Ruby capability in terms of symbolic computation?
