addlistener - addlistener Add listener for event.
el = addlistener(hSource, Eventname, callbackFcn) creates a listener
for the event named Eventname. The source of the event is the handle
object hSource. If hSource is an array of source handles, the listener
responds to the named event on any handle in the array. callbackFcn
is a function handle that is invoked when the event is triggered.
el = addlistener(hSource, PropName, Eventname, Callback) adds a
listener for a property event. Eventname must be one of
'PreGet', 'PostGet', 'PreSet', or 'PostSet'. Eventname can be
a string scalar or character vector. PropName must be a single
property name specified as string scalar or character vector, or a
collection of property names specified as a cell array of character
vectors or a string array, or as an array of one or more
matlab.metadata.Property objects. The properties must belong to the
class of hSource. If hSource is scalar, PropName can include dynamic
properties.
For all forms, addlistener returns an event.listener. To remove a
listener, delete the object returned by addlistener. For example,
delete(el) calls the handle class delete method to remove the listener
and delete it from the workspace.
addlistener binds the listener's lifecycle to the object that is the
source of the event. Unless you explicitly delete the listener, it is
destroyed only when the source object is destroyed. To control the
lifecycle of the listener independently from the event source object,
use listener or the event.listener constructor to create the listener.

eq - == (EQ) Test handle equality.
Handles are equal if they are handles for the same object.
H1 == H2 performs element-wise comparisons between handle arrays H1 and
H2. H1 and H2 must be of the same dimensions unless one is a scalar.
The result is a logical array of the same dimensions, where each
element is an element-wise equality result.
If one of H1 or H2 is scalar, scalar expansion is performed and the
result will match the dimensions of the array that is not scalar.
TF = EQ(H1, H2) stores the result in a logical array of the same
dimensions.

findobj - FINDOBJ Find objects matching specified conditions.
The FINDOBJ method of the HANDLE class follows the same syntax as the
MATLAB FINDOBJ command, except that the first argument must be an array
of handles to objects.
HM = FINDOBJ(H, <conditions>) searches the handle object array H and
returns an array of handle objects matching the specified conditions.
Only the public members of the objects of H are considered when
evaluating the conditions.

findprop - findprop Find property of MATLAB handle object.
p = findprop(H,PropName) finds and returns the matlab.metadata.Property
object associated with property name PropName of scalar handle object H.
PropName can be a string scalar or character vector. It can be the
name of a property defined by the class of H or a dynamic property
added to scalar object H.
If no property named PropName exists for object H, an empty
matlab.metadata.Property array is returned.

H2. H1 and H2 must be of the same dimensions unless one is a scalar.
The result is a logical array of the same dimensions, where each
element is an element-wise >= result.
If one of H1 or H2 is scalar, scalar expansion is performed and the
result will match the dimensions of the array that is not scalar.

result.

of a handle array and has not yet been initialized.

le - <= (LE) Less than or equal relation for handles.
Handles are equal if they are handles for the same object. All
comparisons use a number associated with each handle object. Nothing
can be assumed about the result of a handle comparison except that the
repeated comparison of two handles in the same MATLAB session will
yield the same result. The order of handle values is purely arbitrary
and has no connection to the state of the handle objects being
compared.
H1 <= H2 performs element-wise comparisons between handle arrays H1 and
H2. H1 and H2 must be of the same dimensions unless one is a scalar.
The result is a logical array of the same dimensions, where each
element is an element-wise >= result.
If one of H1 or H2 is scalar, scalar expansion is performed and the
result will match the dimensions of the array that is not scalar.
TF = LE(H1, H2) stores the result in a logical array of the same
dimensions.

listener - listener Add listener for event without binding the listener to the source object.
el = listener(hSource, Eventname, callbackFcn) creates a listener
for the event named Eventname. The source of the event is the handle
object hSource. If hSource is an array of source handles, the listener
responds to the named event on any handle in the array. callbackFcn
is a function handle that is invoked when the event is triggered.
el = listener(hSource, PropName, Eventname, callback) adds a
listener for a property event. Eventname must be one of
'PreGet', 'PostGet', 'PreSet', or 'PostSet'. Eventname can be a
string sclar or character vector. PropName must be either a single
property name specified as a string scalar or character vector, or
a collection of property names specified as a cell array of character
vectors or a string array, or as an array of one ore more
matlab.metadata.Property objects. The properties must belong to the
class of hSource. If hSource is scalar, PropName can include dynamic
properties.
For all forms, listener returns an event.listener. To remove a
listener, delete the object returned by listener. For example,
delete(el) calls the handle class delete method to remove the listener
and delete it from the workspace. Calling delete(el) on the listener
object deletes the listener, which means the event no longer causes
the callback function to execute.
listener does not bind the listener's lifecycle to the object that is
the source of the event. Destroying the source object does not impact
the lifecycle of the listener object. A listener created with listener
must be destroyed independently of the source object. Calling
delete(el) explicitly destroys the listener. Redefining or clearing
the variable containing the listener can delete the listener if no
other references to it exist. To tie the lifecycle of the listener to
the lifecycle of the source object, use addlistener.

lt - < (LT) Less than relation for handles.
H1 < H2 performs element-wise comparisons between handle arrays H1 and
H2. H1 and H2 must be of the same dimensions unless one is a scalar.
The result is a logical array of the same dimensions, where each
element is an element-wise < result.
If one of H1 or H2 is scalar, scalar expansion is performed and the
result will match the dimensions of the array that is not scalar.

ne - ~= (NE) Not equal relation for handles.
Handles are equal if they are handles for the same object and are
unequal otherwise.
H1 ~= H2 performs element-wise comparisons between handle arrays H1
and H2. H1 and H2 must be of the same dimensions unless one is a
scalar. The result is a logical array of the same dimensions, where
each element is an element-wise equality result.
If one of H1 or H2 is scalar, scalar expansion is performed and the
result will match the dimensions of the array that is not scalar.

notify - NOTIFY Notify listeners of event.
NOTIFY(H, eventname) notifies listeners added to the event named
eventname for handle object array H that the event is taking place.
eventname can be a string scalar or character vector.
H is the array of handles to the event source objects, and 'eventname'
must be a character vector.
NOTIFY(H,eventname,ed) provides a way of encapsulating information
about an event which can then be accessed by each registered listener.
ed must belong to the EVENT.EVENTDATA class.
