There are four possible transition states, but only three are (confusingly/incorrectly) described. Assuming the following:
- a 00 transition yields 0
- a 01 transition yields 0
- a 10 transition yields -k
- a 11 transition yields +k
where k is 3*t/2, then:
t = 8;
x = [1 1 1 0 0 0];
dx = diff(x);
hihi = ~dx & x(2:end);
hilo = dx < 0;
re = (hihi - hilo)*3*t/2
