Event and Listener Methods

For information on how to use the notify and addlistener methods, see “Events and

Listeners Syntax” on page 11-22.

Relational Methods

TF = eq(H1,H2)

TF = ne(H1,H2)

TF = lt(H1,H2)

TF = le(H1,H2)

TF = gt(H1,H2)

TF = ge(H1,H2)

The handle class overloads these functions to support equality tests and sorting on

handles. For each pair of input arrays, these functions return a logical array of the same

size. Each element is an element-wise equality or comparison test result. The input arrays

must be the same size or one (or both) can be scalar. The method performs scalar

expansion as required. For more information on handle class relational methods, see

relationaloperators.

Test Handle Validity

Use the isvalid handle class method to determine if a variable is a valid handle object.

For example, in the statement:

B = isvalid(H)

B is a logical array in which each element is true if, and only if, the corresponding

element of H is a valid handle. B is always the same size as H.
