So i have this:
xd = -20:1:20;
yd = -20:1:20;
[x,y] = meshgrid(xd,yd);
A = 0.3;
B = 1;
C = -9;
z = 1./(1+exp(-1*(A*x + B*y + C)));
And I want to pull data that has a value of 1 and put it into one matrix, and then pull data with values of 0 and stick it into another matrix so that i can plot them but I dont know how to, any suggestions?

But then how do i plot the values when theyre either approaching 0 or 1.
also im on discord if youd be down to just talk me through it.

mapNear1 = abs(z - 1) < someTolerance;
mapNear0 = abs(z) < someTolerance;
