Hi all,
I need matlab code for sending phase masks on SLM(after reducing resolution of SLM, to 40 by 40) for an image using phase variation of 0 and pi only. Can any one help please?

Hi,

You can look at that tutorial How to control an SLM with Matlab/Octave using Psychtoolbox.
However, I do not use Matlab anymore, so I do not know if it still works the same way.
