You can open multiple plot windows using the
figure (1); fplot (@sin, [-10, 10]); figure (2); fplot (@cos, [-10, 10]);
creates two figures, with the first displaying a sine wave and the second a cosine wave. Figure numbers must be positive integers.
Create a new figure window for plotting.
If no arguments are specified, a new figure with the next available number is created.
If called with an integer n, and no such numbered figure exists, then a new figure with the specified number is created. If the figure already exists then it is made visible and becomes the current figure for plotting.
Multiple property-value pairs may be specified for the figure object, but they must appear in pairs.
The optional return value h is a graphics handle to the created figure object.
