Function meanDiff

meanDiff(a: Num, b: Num): { diff: Writable<Num>; mean: Writable<Num> }
(a, b) → {mean: (a+b)/2, diff: a−b}. Square linear iso; each write is the inverse change of basis, so mean and diff are cross-channel invariant.
Parameters
- a: Num
- b: Num
Returns { diff: Writable<Num>; mean: Writable<Num> }
