Description |
---|---|---|
ipClusterer |
Clusterer to be used | |
nCluster |
DINT |
Cluster ID of the cluster the center of which is requested |
ipCenter |
Reference To ITcVnContainer |
Returns the cluster center (ContainerType_Vector_REAL or ContainerType_Vector_LREAL depending on the floating point type internally used by the clusterer) |
hrPrev |
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) |
Further information
The function F_VN_GetClusterCenter
returns the center of a cluster.
Parameter
Clusterer model
The cluster whose center is to be calculated must be contained in the previously trained model ipClusterer
.
Cluster ID
The ID of the corresponding cluster is transferred to nCluster
.
Cluster center
The center of the cluster is returned via the reference ipCenter
. The type of container returned is ContainerType_Vector_REAL
or ContainerType_Vector_LREAL
, depending on the data type used internally in ipClusterer
.
Application
The center of the third cluster in a Clusterer model can be determined as follows:
hr := F_VN_GetClusterCenter(
ipClusterer := ipClusterer,
nCluster := 2,
ipCenter := ipCenter,
hrPrev := hr);
