We want to plot the slopefield of the first order ODE
over a user-designated window
- Make the appropriate changes in init.m.
ftx = ''; (RHS of
Save then type init in the command window to initialize the
variables (or copy-and-paste in the Emporium).
initax = [,,,]; (desired window size)
(Unles otherwise specified, we will use N = 20; as originally
written in init.m.
- Type slopef(ftx,N)
- If the resulting plot does not show all of the general behavior
for the ODE solution, you may have to choose new and/or -values
for initax, then do Items 1 and 2 again.
