I have been using the following method to create L(x,t)
If I do image(L0) I get an x,t plot of a drifting cosine wave grating.
The grating is actually a pattern of fuzzy bars; I have been ignoring the
y dimension (because the grating is vertical: y has no effect on the
luminance). However now I want to use it, and get L0(x,y,t).
I don't really understand outer, and my experiments with it have not
worked. The basic idea is that I want a 19 frame movie and each frame
is a 66 x 31 image of a cosine grating. How to do it?
Thanks very much for any help!
