There are many examples on how to use ode45 on the net, you can start
by studying there.
I have few basic examples on my web site below, start from exmaple 53.
http://12000.org/my_notes/mma_matlab_control/howto.htm
to compare the result, plot all solution on the same plot. you can use
the command 'hold on' to do that.
