iscom (External Interfaces Reference)

Determine if input is COM object

Syntax

```
tf = h.iscom
tf = iscom(h)
```

Description

tf = h.iscom returns logical 1 (true) if the input handle, h, is a COM or ActiveX object. Otherwise, iscom returns logical 0 (false) .

tf = iscom(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 iscom returns true:

h = actxserver('excel.application');

h.iscom
ans =
