Psychtoolbox interfaces between Matlab or Octave and the computer hardware. The
PTB core routines provide access to the display frame buffer and color lookup
table, reliably synchronize with the vertical screen retrace, support
sub-millisecond timing, expose raw OpenGL commands, support video playback and
capture as well as low-latency audio, and facilitate the collection of observer
responses. Ancillary routines support common needs like color space
transformations and the QUEST threshold seeking algorithm.
Psychtoolbox 3.0.18 Beta update “Experimental Taylor expansion “ SP5 was released at 22nd May 2022.

Celia Foster was giving a 12 minute quick presentation about what’s new
in Psychtoolbox since the last update at VSS 2019, as part of the
Mathworks/INCF 1 hour session. Videos of much of that session may become
available later, after editing/cutting etc.
For now, a video of Celia’s practice talk, only containing the 12 minute
Psychtoolbox bit, without Q & A, is available on YouTube under this link:

Thanks to Mathworks, INCF and the volunteers in the room for hosting
this session.
Enjoy!
