HOW CAN U HAVE PSYCHOTOOLBOX ON MATLAB 64 HOW TO
Each new experiment simply implements callback functions that handle how to draw the screen, what to do when a subject responds etc. The task library simplifies writing experiments since it takes care of timing, trials, synching with digital pulses, interfacing with eye-trackers etc.

We have a low-level library for displaying stimuli and accessing hardware as well as a task library which sits on top of that. Functions are simple so that they are easier to maintain against OS upgrades (the back end of MGL was rewritten a few years ago using objective-C so that we could be 64-bit compliant).Ģ) Task library.

New functionality typically gets added as a separate function so we don't risk breaking existing code. This was so that it would be easy to hack in the future and for others. Something like the philosophy behind UNIX where kitchen sink type functions are frowned upon. So a major design goal was to keep each function as atomic and simple as possible - every function is one C/MEX file that has OS specific code clearly separated out, typically as a separate function. We were aiming to make the code as simple as possible, so that we and others could extend functionality as easily as possible. When finished, with displaying the stimuli, you simply close the screen:Ī couple of things that distinguish MGL from other packages for doing psychophysics experiments using Matlab.ġ) Simple standalone functions. % This function will wait till the end of the screen refresh % The above is drawn on the back-buffer of the double-buffered display % To make it show up you flush the display. for a monitor 57 cm away, which has width and height of 16 and 12 cm). % Select the coordinate frame for drawing % (e.g. % 1 would be full screen in the main display % 2 would be full screen in a secondary display, etc. % Open the screen, 0 specifies to draw in a window. A basic “hello world” program can be written in four lines: The best way to see whether it will be useful to you is to try out the mglTest programs and also the sample experiment testExperiment. If you are using an older version of Mac OS or Matlab and are having trouble getting MGL to run, you may need to recompile. If we encounter any compatibility issues, that information will generally be posted here. In general, we stay reasonably up to date with releases of Mac OS and Matlab.

Mgl works with the latest versions of Mac OS X (10.6-10.8) and with the latest versions of Matlab (7.4-8.1) as of.
