I want to obtain the admittance matrix of an external system seen from boundary ports.
I would like to transfer the output data (including the magnitudes and phase angles) to MATLAB and fit them via Vector Fitting to obtain a frequency dependent network equivalent. In ATPDraw, the out file is putted in a *.lis file that can be used. Although in EMTP_RV, the output data (related to plot curves) is putted in *.m file and a *.mda file, but I don't know how use them. The *.mda file is not opened by office Access software. I really would be grateful if you can help me.Thanks a lot for your kind attention in advance.I am waiting for your reply soon.
