Single vector input

x = linspace(0,2*pi,50)
y = exp(0.3*x).*sin(3*x)
stem(y)

Specifying line and area colors

options = struct
options.barFill = 'gray'
options.markerStroke = 'gray'
options.markerFill = 'lightgray'
x = 1:0.3:9
y = exp(x).* sin(x)
stem(y, options)

Changing base level

options = struct('barBase', 3)
y = linspace(-2*pi,2*pi,50)
stem(y, options)

Matrix input

x = linspace(0,2*pi,50)
y = [cos(x); 0.5*sin(x)]
stem(y')
