This function plots formatted histograms. It's similar to hist, but with more options for FaceColor, BarWidth, LineStyle, FaceAlpha, etc.

Description
histf(Y) bins the elements in vector Y into 10 equally spaced containers and returns the number of elements in each container as a row vector. If Y is an m-by-p matrix, histf treats the columns of Y as vectors. No elements of Y can be complex or of type integer.

histf(Y,x) where x is a vector, returns the distribution of Y among length(x) bins with centers specified by x. For example, if x is a 5-element vector, histf distributes the elements of Y into five bins centered on the x-axis at the elements in x, none of which can be complex.

histf(Y,nbins) where nbins is a scalar, uses nbins number of bins.

histf(...,'BarWidth',BarWidth) specifies the width of bars as a fraction of total space available for each bar. Default BarWidth is 1.

histf(...,'FaceColor',FaceColor) specifies face color as a short name, long name, or RGB triple.

histf(...,'EdgeColor',EdgeColor) specifies edge coloras a short name, long name, or RGB triple.

histf(...,'LineStyle',LineStyle) specifies line style of bar edges. Can be '-' (default), ':', '--', '-.', or 'none'.

histf(...,'LineWidth',LineWidth) specifies line width of bar edge in points. Default LineWidth is 0.5 points.

histf(...,'FaceAlpha',FaceAlpha) specifies transparency value of bar faces. FaceAlpha must be a scalar between 0 and 1. Default value is 1.

histf(...,'EdgeAlpha',EdgeAlpha) specifies transparency value of bar edges. EdgeAlpha must be a scalar between 0 and 1. Default value is 1.

histf(...,'Alpha',Alpha) sets FaceAlpha and EdgeAlpha to Alpha.

[n,xout,h] = histf(...) returns vectors n and xout containing the frequency counts and the bin locations. h is the handle of the newly plotted histogram.
