How would I go about plotting Tupper's self-referential formula in MATLAB?

The formula itself is:
1/2 < floor(mod(floor(y/17)*2^(-17*floor(x)-mod(floor(y), 17)),2))
How could I plot this in an x,y Cartesian graph in matlab with axes:
0<= x <= 105
n <= y <= n+16

Hi Nathan, you would first have to find the values of (x,y) that satisfy that inequality, under those constraints. Assuming you have those points, you can construct a matrix of binary values and simply plot that.
points = randi([0 1], 106, 17);
imagesc(points);
colormap gray; axis equal;
