wdOrientLandscape is part of an enumeration. It's value is actually 1.
The proper usage for CentimetersToPoints should be
actXword.CentimetersToPoints(1)
but this gives an error. I'm not sure why. However, this is easy enough to set without calling the function as 1 cm is equal to 28.3464567 points.
I'm not sure of a good guide. The command structure for the COM interface to Word is quite similar to the VBA commands - you just have to be careful. Some thoughts that come to mind:
1. You can never assume that the root object is known. For example, in VBA you generally don't have to supply the base "Application" argument. This is why you would need to supply actXword.CentimetersToPoints rather than just CentimetersToPoints when calling the function from Matlab.
2. You have to be careful with collections and how you index into them. In VBA you can often supply a text argument to index into a collection (e.g., reference a worksheet by its name in Excel). This does not work in the COM interface. You have to index into the Item property of the collection.
3. You also have to be careful with enumerations (see above). To get enumeration values, open the VBA editor and go to the Immediate window. To get the value for an enumeration type
?enumerationName
This will show you the actual numerical value to use. You can also look these up on the web.
4. A useful function in Matlab is methodsview(). This can give you information about what methods an object supports.
Good luck,
