som_neighf

H = som_neighf(sMap,radius,neigh,ntype)

SOM_NEIGHF Return neighborhood function values.

 H = som_neighf(sMap,[radius],[neigh],[ntype]);
 
  Input and output arguments ([]'s are optional): 
   sMap     (struct) map or topology struct
   [radius] (scalar) neighborhood radius (by default, the last used value
                     in sMap.trainhist is used, or 1 if that is unavailable)
   [neigh]  (string) neighborhood function type (by default, ..., or 
                     'gaussian' if that is unavailable)
   [ntype]  (string) 'normal' (default), 'probability' or 'mirror'

   H        (matrix) [munits x munits] neighborhood function values from 
                     each map unit to each other map unit
