histfit
              Plot histogram with superimposed distribution fit.
 histfit (x) plots a histogram of the values in the vector
 x using the number of bins equal to the square root of the number of
 non-missing elements in x and superimposes a fitted normal density
 function.
 histfit (x, nbins) plots a histogram of the values in the
 vector x using nbins number of bins in the histogram and
 superimposes a fitted normal density function.
 histfit (x, nbins, distname) plots a histogram of
 the values in the vector x using nbins number of bins in the
 histogram and superimposes a fitted density function from the distribution
 specified by distname.
 histfit (ax, …) uses the axes handle ax to plot the
 histogram and the fitted density function onto followed by any of the input
 argument combinations specified in the previous syntaxes.
 h = histfit (…) returns a vector of handles h, where
 h(1) is the handle to the histogram and h(1) is
 the handle to the density curve.
 Note: calling fitdist without any input arguments will return a cell
 array of character vectors listing all supported distributions.
