History function for ODE45

Hi everyone

I am currently solving an equation using ODE45 in matlab. I had a question though.

Is that possible to define a history function for ODE45 instead of initial conditions?

Thank you in advance for you help.

Regards,

Since ode45 solves systems of first-order differential equations on the standard form the history does not matter, so I've never seen a way to incorporate that into ode45-calls. If your differential equations depend on the history you perhaps have a delay-differential equation - which can be handled with dde23, look at the help and documentation to that function...
