Using The Applet
The user can re-set four parameters by left-clicking in
the four control panel windows,
deleting the current value and typing in the
new value.
After changing any parameter, left-click on Redraw button.

(Apart from the restriction
n0 > dn the range restrictions are elastic: the
accuracy
may degrade, or in the case of large dn the applet may become very
slow.)
The Increment T button increases the time by 1/64 units and redraws.
The Default plot is |Psi(x,t)|2, the probability
distribution as a function of x, at the current time
t.
Left-click on the Plot button to obtain a menu of other diagnostic
plots.
The text panel displays diagnostic data at the current time for Psi
and |Psi(x,t)|2 plots
and descriptive text for other plots.
