Hey guys,
I was just wondering if anyone knows how to set the initial conditions for ode45() if you know f(1.5) but NOT f(0) Currently I have >> ode45(f, [0 1 1.8 2.1], [1.5 .5]) But this creates the following error: ??? Error using ==> funfun/private/odearguments @(T,Y) (TEXP(T))/(Y+EXP(Y)) must return a column vector. Thanks.

You should be able to solve on arbitrary time intervals [ta,tb] going forwards or backwards in time. Your error looks like it's coming from your function f. What does it look like?

I was able to fix it. Apparently i was using / in f() instead of ./.
Thanks for your help.
