As it is well known, it is possible to define a function that remembers its values once its evaluated, using the following code:
During the day I evaluate
f[x], for many
x's, and I do not know/remember at which values of
x I evaluated this. These values wont need to be evaluated again until I close mathematica, but if I close it, they will be lost. Is there a way to avoid this? To store these values somehow, so that I can use them the next time I open mathematica?
