Different initial condition than y(0) for ode45?

[adityagaddam]

Hi,

I am trying to solve a differential equation using ode45. But I need to use an initial condition other than y(0). Is there any way to do this? An example would be solving y^2 with an intial value of y(5) = 2. Matlab only seems to allow you to specify values for y(0)

Thanks,
Aditya
