variogram calculates the isotropic and anisotropic experimental variogram in various dimensions.
Syntax:
d = variogram(x,y)
d = variogram(x,y,'pn','pv',...)
The function uses parseargs (objectId=10670) by Malcolm wood as subfunction.
Currently, the function calculates all variogram values at one step. While this is fast for small data sets (n<2000), it may fail on large data sets owing to memory constraints. For large datasets you may thus want to use the 'subsample' option.

| Version | Publié le | Notes de version | Action |
|---|---|---|---|
| 1.4.0.0 | Bug removed that occurred when calculating the distances for more than two dimensions. |
||
| 1.3.0.0 | removed a bug in calculating the number of angular bins for anisotropic variograms. |
||
| 1.2.0.0 | Removed dependency from IPDM. Fortunately, it is even faster now on my machine. The relatively large memory overhead is still unresolved. Added subsampling option. |
||
| 1.1.0.0 | dependence on consolidator was removed,
|
||
| 1.0.0.0 | removed an error in the calculation of the number of bins |
