Clear current figure window
clf
clf('reset')
clf(fig)
clf(fig,'reset')
figure_handle = clf(...)
clf deletes from the current
figure all graphics objects whose handles are not hidden (i.e., their HandleVisibility property
is set to on).
clf('reset') deletes from the current figure all
graphics objects regardless of the setting of their HandleVisibility
property and resets all figure properties except Position, Units, PaperPosition, and PaperUnits to their default
values.
clf(fig) or clf(fig,'reset') clears
the single figure with handle fig.
figure_handle = clf(...) returns
the handle of the figure. This is useful when the figure IntegerHandle property
is off because the noninteger handle becomes invalid
when the reset option is used (i.e., IntegerHandle is
reset to on, which is the default).
Use Clear Figure from the figure window's Edit menu to clear the contents of a figure. You can also create a desktop shortcut to clear the current figure with one mouse click. See Rerun Favorite Commands.
The clf command behaves the same way when
issued on the command line as it does in callback routines —
it does not recognize the HandleVisibility setting
of callback. This means that when issued from within
a callback routine, clf deletes only those objects
whose HandleVisibility property is set to on.
