toolbox for vision research -- arch/interpreter independent part

Psychophysics Toolbox Version 3 (PTB-3) is a free set of Matlab and GNU/Octave functions for vision research. It makes it easy to synthesize and show accurately controlled visual and auditory stimuli and interact with the observer.

The Psychophysics Toolbox interfaces between Matlab or Octave and the computer hardware. The Psychtoolbox's core routines provide access to the display frame buffer and color lookup table, allow synchronization with the vertical retrace, support millisecond timing, allow access to OpenGL commands, and facilitate the collection of observer responses. Ancillary routines support common needs like color space transformations and the QUEST threshold seeking algorithm.

This package contains architecture independent files (such as .m scripts)

Package version:3.0.9+svn2579.dfsg1-1

Real-time scheduling and memory locking priorities

For better control over timing, PTB tries to use real-time scheduling
policy for the running process and perform memory locking of necessary
memory resources.  To allow for such operations to be performed there
are few alternative solutions
