initializing mwArray as "empty"

Hi,
i have a problem when using a specific Matlab .dll in C++. I need to have an empty mwArray variable (empty as representing [] in MATLAB) to be able to call it. I just do not know how to create an empty mwArray.
Any idea would be greatly appreciated, tanks in advance. ...

Does the default constructor not do this? The help states:
mwArray()
Description
Construct empty array of type mxDOUBLE_CLASS.

Well, if so i did not recognize it ... i read somewhere that this would give an "uninitialized" mwArray... what would not necessarily mean "empty" in MATLAB i guess. The MATLAB dll however throws an exception when i try that, but that may be for another reason as well. I am not very deep inside the m-code that i would like to call. However, if the the help says it's empty i'll take that.
Thanks a lot, (i still wonder why i did not find it ... ) ...

I tend to only post as an answer if I am confident it is an actual answer. In this case I just took a quick look in the help and threw that out as a query without having tried it out for myself.

The default constructor
myArray( );
should do this.
