I am trying to evaluate J for doing mathematics vs. Mathematica. I own the Home edition of Mathematica. At the moment, I am trying to teach myself higher maths with an eye towards completing my maths degree online. I never finished my degree many moons ago. I like the notebook structure and multi-paradigm approach in Mathematica, but I am gravitating towards J's succinctness and analogy to learning it's symbols akin to mathematics' symbols. Iverson's 'Notation as a Tool of Thought' really grabbed me. My latest curiosity about J, if I understand it correctly, is that J is provided as an executable for several platforms. That it was written in C. Now, does it implement standard c maths libraries optimized for speed and accuracy? How does the linux version compare to Mathematica in terms of doing certain operations, say large arrays, for signal processing, from a time and numerical accuracy index? Where can I find a listing of the libraries it uses, in the source headers? Thank you.
