Determine whether input is COM interface
tf = isinterface(h)
tf = isinterface(h) returns logical 1 (true)
if handle h is a COM interface. Otherwise, returns
logical 0 (false).

Test an instance of a Microsoft Excel® application.
h = actxserver('Excel.Application');
isinterface(h)
MATLAB® displays false, indicating object h is
not an interface.
Test a workbooks object
w = get(h,'workbooks');
isinterface(w)
MATLAB displays true, indicating object w is
an interface.
