isinterface (External Interfaces Reference)

Determine if input is COM interface

Syntax

```
tf = h.isinterface
tf = isinterface(h)
```

Description

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

tf = isinterface(h) is an alternate syntax for the same operation.

Examples

Create a COM server running Microsoft Excel. The actxserver function returns a handle h to the server object. Testing this handle with isinterface returns false:

h = actxserver('excel.application');

h.isinterface
ans =
   0

Create an interface to workbooks, returning handle w. Testing this handle with isinterface returns true:

w = h.get('workbooks');

w.isinterface
ans =
   1
