minima = som_dmatminima(sM,U,Ne)
SOM_DMATMINIMA Find clusters based on local minima of U-matrix.
minima = som_dmatminima(sM,[U],[Ne])
Input and output arguments ([]'s are optional):
sM (struct) map struct
U (matrix) the distance matrix from which minima is
searched from
size msize(1) x ... x msize(end) or
2*msize(1)-1 x 2*msize(2)-1 or
munits x 1
Ne (matrix) neighborhood connections matrix
minima (vector) indeces of the map units where locla minima of
of U-matrix (or other distance matrix occured)
