Consider I have this code :
f=2 f[1.5]=6 f=4
What is the simplest way to save the array f defined on those three numbers in a file ? (in my case, I will have a lot of values, not juste three but the indices of my array will be regularly spaced).
How can I tell in a simple way to mathematica I want to save the full array f ? Am I forced to somehow loop on the indices ?
