The left graphic shows the upper-left half of an
n×n
matrix of hysterons. A hysteron is a nonideal relay or Schmitt trigger, with two states: {off, 0, yellow} or {on, 1, red}.
Change the
x
value with its slider. On the left you see how the hysterons are switched on or off as you increase or decrease
x
. The right graphic shows the corresponding hysteresis curve. At a given point
x
, the
y
value is the proportion of switched-on hysterons. This value depends on the history of
x
. The curve stores the history of the last 300 points and the red point is the current point.
