20 ## @deftypefn {Function File} {@var{h} =} gcf () |
6895 | 21 ## Return the current figure handle. If a figure does not exist, create |
22 ## one and return its handle. The handle may then be used to examine or | |
23 ## set properties of the figure. For example, | |
24 ## | |
25 ## @example | |
26 ## @group | |
27 ## fplot (@@sin, [-10, 10]); | |
28 ## fig = gcf (); | |
29 ## set (fig, "visible", "off"); | |
30 ## @end group | |
31 ## @end example | |
32 ## | |
33 ## @noindent | |
34 ## plots a sine wave, finds the handle of the current figure, and then | |
35 ## makes that figure invisible. Setting the visible property of the | |
36 ## figure to @code{"on"} will cause it to be displayed again. | |
