Plot discrete sequence data
A two-dimensional stem plot displays data as lines extending from a baseline along the x-axis. A circle (the default) or other marker whose y-position represents the data value terminates each stem.
plots the data sequence
Y as stems that extend from equally spaced and automatically generated values along the x-axis. When
Y is a matrix,
stem plots all elements in a row against the same x value.
X versus the columns of
Y are vectors or matrices of the same size. Additionally,
X can be a row or a column vector and
Y a matrix with
