Stem and leaf plot

This is a simple utility for making stem and leaf plots output to the command window.

Plots stem and leaf plot to command window

stemleafplot(v)
stemleafplot(v,p)

STEMLEAFPLOT plots stem-leaf plots of the input V to the command window.
Leaf precision may be defined by the user. Note that inputs will be
rounded to the nearest leaf unit (http://en.wikipedia.org/wiki/Stemplot).

INPUT
V : Array of numerical inputs (NaN values are ignored)

OPTION
P : Leaf precision (defined as integer power of 10)
Stem precision (by default) is 10^(P+1).
P is automatically rounded at the beginning of the function.
Leaf and stem units are printed at the bottom of the graph.
Examples: P = -3 rounds V to the nearest 10^-3 = 0.001
P = 3 rounds V to the nearest 10^3 = 1000
[DEFAULT: P = 0]

OUTPUT
Command window output

EXAMPLES
% Stem-leaf plot of V with unit precision
V = 10.*randn(1,50);
stemleafplot(V)

% Stem-leaf plot of V with precision of 0.1
V = randn(1,50);
stemleafplot(V,-1)

% Stem-leaf plot of V with precision of 100
V = 5000.*randn(1,50);
stemleafplot(V,2)
