You may want to check out the just-released Micro-Cap 8 program by Spectrum Software to integrate your Z-parameters matrix into a complete analyses/simulator tool. Depending on your formats, MC8 can handle S, Y, Z, G, or H-parameters. Check out the new features of MC8 at http://www.spectrum-soft.com/features.shtm. A visit to this web page will be an eye-opener. I have used Micro-Cap for over 15 years and highly recomment it as a competent, easily used, competitively priced program. I have found the plotting capabilitites and many analysis functions superior to programs costing five times as much. Mike Michael L.
