Produce 2-D plots.

Many different combinations of arguments are possible. The simplest form is

> > `plot (Y)`

where the argument is taken as the set of `Y` coordinates and the `X`
coordinates are taken to be the range '`1:numel (Y)`'.

If more than one argument is given, they are interpreted as

> > `plot (Y, PROPERTY, VALUE, ...)`

or

> > `plot (X, Y, PROPERTY, VALUE, ...)`

or

> > `plot (X, Y, FMT, ...)`

and so on. Any number of argument sets may appear. The `X` and `Y` values are
interpreted as follows:

- If a single data argument is supplied, 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.

- If `X` and `Y` are scalars, a single point is plotted.

- 'squeeze()' is applied to arguments with more than two dimensions, but no
  more than two singleton dimensions.

- If both arguments are vectors, the elements of `Y` are plotted versus the
  elements of `X`.

- If `X` is a vector and `Y` is a matrix, then the columns (or rows) of `Y` are
  plotted versus `X`. (using whichever combination matches, with columns tried
  first.)

- If the `X` is a matrix and `Y` is a vector, `Y` is plotted versus the columns
  (or rows) of `X`. (using whichever combination matches, with columns tried
  first.)

- 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.

Multiple property-value pairs may be specified, but they must appear in pairs.
These arguments are applied to the line objects drawn by 'plot'. Useful
properties to modify are `"linestyle"`, `"linewidth"`, `"color"`, `"marker"`,
`"markersize"`, `"markeredgecolor"`, `"markerfacecolor"`. The full list of
properties is documented at Line Properties.

The `FMT` format argument can also be used to control the plot style. It is a
string composed of four optional parts:
"\<linestyle\>\<marker\>\<color\>\<;displayname;\>". When a marker is
specified, but no linestyle, only the markers are plotted. Similarly, if a
linestyle is specified, but no marker, then only lines are drawn. If both are
specified then lines and markers will be plotted. If no `FMT` and no
`PROPERTY`/`VALUE` pairs are given, then the default plot style is solid lines
with no markers and the color determined by the `"colororder"` property of the
current axes.

Format arguments:

#### linestyle

- '-' Use solid lines (default).
- '--' Use dashed lines.
- ':' Use dotted lines.
- '-.' Use dash-dotted lines.

#### marker

- '+' crosshair
- 'o' circle
- '\*' star
- '.' point
- 'x' cross
- '|' vertical line
- '\_' horizontal line
- 's' square
- 'd' diamond
- '^' upward-facing triangle
- 'v' downward-facing triangle
- '>' right-facing triangle
- '<' left-facing triangle
- 'p' pentagram
- 'h' hexagram

#### color

- 'k', "black" blacK
- 'r', "red" Red
- 'g', "green" Green
- 'b', "blue" Blue
- 'y', "yellow" Yellow
- 'm', "magenta" Magenta
- 'c', "cyan" Cyan
- 'w', "white" White

#### `";displayname;"`

The text between semicolons is used to set the `"displayname"` property which
determines the label used for the plot legend.

The `FMT` argument may also be used to assign legend labels. To do so, include
the desired label between semicolons after the formatting sequence described
above, e.g., `"+b;Data Series 3;"`. Note that the last semicolon is required
and MathJSLab will generate an error if it is left out.

Here are some plot examples:

> > `plot (x, y, "or", x, y2, x, y3, "m", x, y4, "+")`

This command will plot `y` with red circles, `y2` with solid lines, `y3` with
solid magenta lines, and `y4` with points displayed as `'+'`.

> > `plot (b, "*", "markersize", 10)`

This command will plot the data in the variable `b`, with points displayed as
`'*'` and a marker size of 10.

> > `t = 0:0.1:6.3;`

> > `plot (t, cos(t), "-;cos(t);", t, sin(t), "-b;sin(t);");`

This will plot the cosine and sine functions and label them accordingly in the
legend.

If the first argument `HAX` is an axes handle, then plot into this axes, rather
than the current axes returned by `gca`.

The optional return value `H` is a vector of graphics handles to the created
line objects.

To save a plot, in one of several image formats such as PostScript or PNG, use
the `print` command.
