isprop (COM) - Determine whether input is COM object property

Syntax

Description

tf = h.isprop('propertyname') returns logical 1 (true) if the specified name is a property of COM object h. Otherwise, returns logical 0 (false).

tf = isprop(h, 'propertyname') is an alternate syntax.

COM functions are available on Microsoft Windows systems only.

Examples

Test a property of an instance of a Microsoft Excel application:

h = actxserver('Excel.Application');
isprop(h,'UsableWidth')

MATLAB returns true, UsableWidth is a property.

Try the same test on SaveWorkspace:

isprop(h,'SaveWorkspace')

MATLAB returns false. SaveWorkspace is not a property; it is a method.
