Hello,
I would like to solve an ordinary differential equations (ODE) with a specfic step using the command ode45. The equation has a range between 0 and 2.75 and the intial condition is 1
F=@(R,t)((R/t_a)*((CFS(1,i))/(0.25*taw_0)-R))
[t,R]=ode45(F, [0 2.75], 1)
In this case, Matlab provides a set of values (41 values). For example, t is a set of values range between 0 and 2.75.
How can I specify that I do not want random values of t in the ODE? Here, I want t to range between 0 and 2.75 but I want a step size of 0.25
Thanks,

I'm affraid that is not an option, this question was answered pretty clearly in this post.
If you want specific points I suggest you simply interpolate them.
