function plot (...)
# usage: plot (x, y)
# plot (x1, y1, x2, y2, ...)
# plot (x, y, fmt)
#
# If the first argument is a vector and the second is a matrix, the
# the vector is plotted versus the columns (or rows) of the matrix.
# (using whichever combination matches, with columns tried first.)
#
# If the first argument is a matrix and the second is a vector, the
# the columns (or rows) of the matrix are plotted versus the vector.
# (using whichever combination matches, with columns tried first.)
#
# If both arguments are vectors, the elements of y are plotted versus
# the elements of x.
#
# If both arguments are matrices, the columns of y are plotted versus
# the columns of x. In this case, both matrices must have the same
# number of rows and columns and no attempt is made to transpose the
# arguments to make the number of rows match.
#
# If both arguments are scalars, a single point is plotted.
#
# If only one argument is given, it is taken as the set of y
# coordinates and the x coordinates are taken to be the indices of the
# elements, starting with 1.
#
# To see possible options for FMT please see plot_opt.
#
# Examples:
#
# plot (x, y, "@12", x, y2, x, y3, "4", x, y4, "+")
#
# y will be plotted with points of type 2 ("+") and color 1 (red).
# y2 will be plotted with lines.
# y3 will be plotted with lines of color 4.
# y4 will be plotted with points which are "+"s.
#
# plot (b, "*")
#
# b will be plotted with points of type "*".
