figure(h)does one of the following:

If h is the handle or the Number property value of an existing figure, then figure(h) makes that existing figure the current figure, makes it visible, and moves it on top of all other figures on the screen. The current figure is the target for graphics output.

If h is not the handle and is not the Number property value of an existing figure, but is an integer, then figure(h)creates a figure object and assigns its Number property the value h.

If h is not the handle to a figure and is not a positive integer, then MATLAB returns an error.

h = figure(...)returns the handle to the figure object.
