[hits,ninvalid] = hits(bmus, mmax, values)
HITS Calculate number of occurances of each value.
hits = hits(bmus,[mmax],[values])
h = hits(bmus);
h = hits(bmus,length(sM.codebook));
Input and output arguments ([]'s are optional):
bmus (vector) BMU indeces (or other similar)
[mmax] (scalar) maximum index, default value max(bmus)
(struct) map or topology struct from where the maximum
index is acquired
[values] (vector) values associated with the data (default = 1)
hits (vector) the number of occurances of each index
(or if values are given, their sum for each index)
ninvalid (scalar) number of invalid indeces (NaN, Inf or
<=0 or > mmax)
