DistType Fields |
The DistType type exposes the following members.
Fields| Name | Description | |
|---|---|---|
  | C |
distance = max(|x1-x2|,|y1-y2|)
|
| Fair |
distance = c^2(|x|/c-log(1+|x|/c)), c = 1.3998
|
| Huber |
distance = |x|<c ? x^2/2 : c(|x|-c/2), c=1.345
|
| L1 |
distance = |x1-x2| + |y1-y2|
|
| L12 |
L1-L2 metric: distance = 2(sqrt(1+x*x/2) - 1))
|
| L2 |
