Thanks, this sounds intriguing.  I'm trying it on my recent Intel 
hardware.  Wasn't really clear to me how to get started from the README 
(your docs look extensive but maybe could offer a little more newbie 
handholding...)

Anyway, Here's what I've tried so far:

>> ocl_double (rand (10, 10))
error: ocl_double: error while dynamically loading OpenCL library
  check library path and file name ('lib_path_filename') to point to 
correct OpenCL library file

>> ocl_lib ("lib_path_filename", '/usr/lib64', 'libOpenCL.so.1')

# (this is based on `locate -i libopencl`)

>>  ocl_lib ("assure")
error: ocl_lib: error while dynamically loading OpenCL library
  check library path and file name ('lib_path_filename') to point to 
correct OpenCL library file

Any hints?  I'm on Fedora and have installed relevant-looking stuff from 
"dnf list opencl*".  "clinfo" returns lots of stuff...

thanks,
Colin
