Export Data from HFSS to Matlab

I have been used toobox delivered by Vijay Ramasami for connecting Matlab and HFSS.However,when I run the example:dipole_example,it seems to me that the results have problem
-The simulated resonant frequency of dipole doesn't change through different iterations->I guest it is due to the results have not been updated through iterations

Does anyone experiences similar problems?Could you help me overcome this trouble?
At the moment,I am assigned the mission to develop GA optimizers to optimize antenna design.If anyone find it of interest,could you discuss with me at haidt102(at)yahoo.com

Thanks in advance
