Psychtoolbox:PsychCal.

Calibration routines for monitors, e.g., gamma correction.
For a very simple gamma calibration of a standard monitor with a manually
controlled photometer, use CalibrateMonitorPhotometer.

For advanced calibration, with manual or automatic photometers, with
standard monitors or high precision displays like Bits+,
DataPixx/ViewPixx etc. use CalibrateMonSpd.
