MatHtoolClusteringType

Indicates the type of clustering used by a MATHTOOL

Synopsis

typedef enum {
  MAT_HTOOL_CLUSTERING_PCA_REGULAR,
  MAT_HTOOL_CLUSTERING_PCA_GEOMETRIC,
  MAT_HTOOL_CLUSTERING_BOUNDING_BOX_1_REGULAR,
  MAT_HTOOL_CLUSTERING_BOUNDING_BOX_1_GEOMETRIC
} MatHtoolClusteringType;

Values

• MAT_HTOOL_CLUSTERING_PCA_REGULAR (default) - axis computed via principle component analysis, split uniformly

• MAT_HTOOL_CLUSTERING_PCA_GEOMETRIC - axis computed via principle component analysis, split barycentrically

• MAT_HTOOL_CLUSTERING_BOUNDING_BOX_1_REGULAR - axis along the largest extent of the bounding box, split uniformly

• MAT_HTOOL_CLUSTERING_BOUNDING_BOX_1_GEOMETRIC - axis along the largest extent of the bounding box, split barycentrically

Note

Higher-dimensional clustering is not yet supported in Htool, but once it is, one should add BOUNDING_BOX_{2,3} types
