Q: 

Ruby core Matrix vs NArray's NMatrix

There seems to be two matrix modules in Ruby that I've found

  • Matrix: Part of core Ruby it seems
  • NMatrix: Part of the NArray library

At the moment it seems NMatrix is faster, has some more helpful methods, but require a bit more setup.

Is there anyone with experience of both who can give a rough overview of why I should use one over the other?
