TDistMode

Unit:SDL_matrix
Class:none
Declaration:TDistMode = (dmJaccard, dmManhattan, dmEuclid, dmEuclidSqr, dmDice, dmUserDef);

The type declaration TDistMode defines the possible operating modes of the method CalcDistMat. Currently the following distances can be calculated:

dmJaccard similarity measure first defined by P. Jaccard (sometimes also referred to as Tanimoto coefficient)
dmManhattan Manhattan or city block distance
dmEuclid Euclidean distance
dmEuclidSqr squared Euclidean distance
dmDice the Dice coefficient
dmUserDef any user defined distance
