\r\nHere are two sources of useful MATLAB functions that readers might be interested in.\r\n<\/p>\r\n\r\n
\r\nFirst, an acquaintance at Apple Computer recently told me about the Psychtoolbox. He thought that any researcher using MATLAB to do experiments involving human visual perception might find it useful. I surfed around the web site<\/a> and was impressed with the content and activity evident there.\r\n<\/p>\r\n\r\n \r\nHere's a brief description from the home page<\/a>: \"Psychophysics Toolbox Version 3 (PTB-3) is a free set of Matlab functions for vision research. It makes it easy to synthesize and show accurately controlled visual stimuli and interact with the observer.\"\r\n<\/p>\r\n\r\n \r\nSecond, I saw a link today for the \"Colour Engineering Toolbox\", a set of MATLAB functions written by Phil Green and associated with the book Colour Engineering<\/em>, which was co-edited by Green and Prof. Lindsay MacDonald. Both are with the Colour Imaging Group in the London College of Communication. Dr. Green's functions include colour space conversions for a few device-independent spaces, white-point utility functions, mathematical utilities useful for colour computations, colour difference and CIECAM02 computations, and a few psychophysics functions related to experiment design and associated statistics.\r\n<\/p>\r\n\r\n \r\nThere's lots of good MATLAB stuff out there, so don't think you have to implement everything yourself. In addition to Internet search engines, be sure to check out the MATLAB Central File Exchange<\/a>.\r\n<\/p>","protected":false},"excerpt":{"rendered":" \r\nHere are two sources of useful MATLAB functions that readers might be interested in.\r\n\r\n\r\n\r\nFirst, an acquaintance at Apple Computer recently told me about the Psychtoolbox.
