Problem: Horrible slowdowns when using scatter() in a script that you want to publish Solution: Don't use scatter. Use plot(x,y,'.') instead.

Assume you have a custom function, say, hill.m, that looks like this:
function r = hill(x,xdata)
A = x(1);
k = x(2);
n =x(3);
r = A*xdata.^n;
r = r./(xdata.^n + k^n);
% when xdata is negative, return 0
ping -t 1 -q google.com | grep "0.0% packet loss" | wc -l
