摘要：
A method of classifying particles indicated on a two-dimensional frequency distribution map into particle clusters, includes the steps of: dividing the particles into a first cluster and a second cluster by a line containing a mode coordinate of the particles, presuming a third cluster so that the first and third clusters are symmetrical with respect to the mode coordinate, calculating variance and covariance of a cluster including the first and third clusters to obtain an ellipse region surrounding the first and third clusters based on the calculated variance and covariance, and determining the particles in the obtained ellipse region as a particle cluster.
