From this ODE
How do I write a Matlab program that calculates p at time 1.5 time units given a value of k3. I want to do a Matlab function that takes k3 as input and outputs p (1.5)?
Given the following s0 = 2.2, e0 = 2.8, k1 = 11 och k2 = 1.6.
With start values s (0) = s0, e (0) = e0, c (0) = c0 = 0 and p (0) = p0 = 0

Why not? They are developed by experts in the field, that have gone to some considerable lengths to provide a suite of different solvers for ODEs with most types of numerical characteristics. If you know the shortcomings of these solvers for your type of ODE then you should also have sufficient competence to "roll your own" solver, but that doesn't fit very well with your "have used Euler's method before".

Have a look at the ODE-examples, both the demos and the corresponding code:
>> odeexamples
That should give you a good starting introduction to how you should go about implementing your ODEs. Then you can also look at the help and documentation to ode45 and its siblings.
