Number of bins

Syntax: BIN\NBINS x xbin xcount n { xmin xmax }
Defaults: xmin = min(x), xmax = max(x)

By default, the bins are defined by their centers, given in vector xbin, which must be strictly monotonically increasing. If the \NBINS qualifier is used, the number of bins, n, is expected. A new vector, xbin, will be created which will have n elements. If the numbers xmin and xmax are not entered, they default to the minimum and maximum of vector x.

xbin[i] = xmin + (i - 1/2)(xmax - xmin) = n  for  i = 1, 2, ..., n.
