  • Mac OSX only supports 64-bit Snow Leopard 10.6.3 or later (discontinued Leopard 10.5 and 32-bit)
  • New functions:
  • Improvements:
  • Examples have been overhauled:
    • Updated so CPU and GPU use the same code (see "Write once, run everywhere")

    • For a complete description of the current examples: Examples
  • API Changes:
    • SUM, PROD, MIN, MAX, ANY, ALL on vector inputs now return GPU scalars instead of CPU scalars.
  • Graphics:
    • PLOT, PLOT3 now accept linestyle string parameter to set color
    • axis rescaling and panning now corrected so that ticks always visible
    • Added GCOLORMAP, GTITLE, GDRAWNOW
