matlab-psychtoolbox-3-nonfree – toolbox for vision research – Matlab binary blobs

[Note: non-standard licensing terms – please verify license compliance]

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 binary builds for Datapixx and Eyelink bindings for Matlab built/supported/distributed by upstream.
