Examples and tricks to implement and speed up ODE and DDEs in MATLAB (website of Dr. LM Shampine at SMU)
GUI for ODE solving (by yours truly)
Passing multiple parameters in ode45 objective function (Bucknell University, Using ODE45, MATLAB Help, pg 9)
Using spline interpolation within ode45 (tips: pass ppform to objective function [using extra parameter tip from above]
and then use ppval to evaluate ppform at the required time)
