Edge defined bins

Syntax: BIN\EDGES x xbin xcount

By default, bins are defined by their centers. If the \EDGES qualifier is used, bins are defined by their edges. The bin edges must be given in vector xbin. The length of xcount will be one less than the length of xbin. A weight vector, w, may be specified if you use the \WEIGHTS qualifier.

If xbin[j] ≤ x[i] < xbin[j+1] then xcount[j] is incremented either by 1, or by the specified weight, w[i].

  Count only if empty
