You can
use ` eulplot.m` for methods other than
the Euler method if you change ` eulerfcn`
accordingly. For instance, if you use the
improved Euler method for the equation
, then the iteration equation is

Consequently, you want to have the following
line in ` initn.m`:
eulerfcn='x+h/2*(t^2+x^2)+h/2*((t+h)^2+(x+h*(t^2+x^2))^2);'
