You don't really give enough information about what kind of function your
want and what the requirements are. In any case, the following is one
approach (with a more interesting sequence of values). Lookup Interpolation
in Help.
L[x_] = Interpolation[{1, 3, 2, 4}, InterpolationOrder -> 1][x]
InterpolatingFunction[{{1, 4}}, "<>"][x]
Plot[L[x], {x, 1, 4}];

Hi,
A simple question: What is the correct way of converting a list into a
function?
For instance, lets say I have some list
L = {1, 2, 3, 4}
and I want a function such that FuncL[1] would return 1, FuncL[2] would
return 2 and so on. So what is the syntax for FuncL?
I need the function for some further manipulation in a situation in which
simply using L[[1]] would not be appropriate.
Thanks,
R. Bhatnagar
