comment Evaluate function from a table
it has no way of knowing that the function is in x. Afaik, you have to either use Composition or else Replace (a.k.a. /.), as shown above. Sorry don't have the time to write full answer.

comment Evaluate function from a table
Not sure I understand (also looking at @bills answer). I try: either explicitly compose like for any "normal function", like ff = #^2 & and then ff[ff[x]] respectively: g=ff[ff[#]]& or use Composition explicitly

comment Evaluate function from a table
try: f[[1]] = #^2 &(you need a pure function for that, see documentation). Also: check out: ConstantArray[0, 4]:) (fwiw: alternatively: f[[1]] /. x -> 2, but I wouldnt recommend that)

comment How to place a matrix under controls (sliders) in a Manipulate?
not sure if I understand: if you use the following in place of your controls, is that what you want? Column[{Control@{{a, 1, "x-Richtung"}, -3, 3}, Control@{{b, 1, "y-Richtung"}, -3, 3}, Control@{{c, 1, "z-Richtung"}, -3, 3}, Dynamic@Style[{{a, 0, 0}, {0, b, 0}, {0, 0, c}} // MatrixForm, FontSize -> 18, FontColor -> Black, TextAlignment -> Left]}]

comment neighbor swapping distance between two strings
I think EditDistance is a bad choice here, for "EditDistance treats transposition as separate deletion and insertion operations", so: EditDistance["ac", "ca"] yields 2, whereas: "Damerau-Levenshtein distance counts transposition as a single operation" (yields 1)

comment how to calculate with just double floating point precision
you might want to use Chop (use 2nd argument to specify tolerance).
