Hello,
I am using the MATLAB 'actxserver' function to establish a connection
to RTDX(for real-time data exchance between MATLAB and a DSP board) and
if say 'h' is my activex object, I use invoke(h) to get a list of
functions I can use in that interface. 
There are some functions that have "pointer(variant)" or something
similiar as the argument to the function.
Anybody know what these are and how I can use these? 

Thanks in advance!
