My question is that if we can place the InterpolatingFunction object into a file so I can use it directly next time even if I have quit kernel? For instance, I solve this function numerically,
s = NDSolve[{y'[x] == y[x] Cos[x + y[x]], y[0] == 1}, y, {x, 0, 30}]
{{y->InterpolatingFunction[{{0.`,30.`}},"<>"]}}
Can I call the result of "y" without recompute differential equation? Of course I can export point value of y to some file and save it later. I am looking forward to a neater way to handle this .
Any idea is appreciated.
