Psychtoolbox-3

Psychophysics Toolbox Version 3 (PTB-3) is a free set of Matlab and GNU Octave functions for vision and neuroscience research. It makes it easy to synthesize and show accurately controlled visual and auditory stimuli and interact with the observer. Some of its functionality is available as part of Python toolkits like PsychoPy. For commercial support and services visit www.psychtoolbox.net. Follow us on Mastodon or Twitter @psychtoolbox

PSFTOLSF Convert a line spread function to a point spread function
lsf = PSFTOLSF(psf,varargin)

This works by convolving a horizontal line with a psf and returning the  
vertical slice through the center.  The spatial support of the lsf is  
equal to the spatial support of the vertical slice through the passed  
psf.  The passed psf should be square.  
  
The returned lsf is normalized to have a peak amplitude of 1.
