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.
