At first i'm so happy that you solved the compile problem. :-)
Now to the problem:
I tried to import data from qucs's S-Parameter simulation(from real *.s2p) to octave(great feature as far) by referring to the example given in that forum. now the problem is it only reads the "real"-part of the complex S-Parameters.
i have worked around it(outputed the imag value seperatly and put it together in octave), but the example in your *.m says it should read complex data too.
so maybe you can have look on to this.
THANKS FOR THIS GREAT TOOL,
btw. I try to write a script that translate *.s2p into *.sch, you can have it when I'm finished.
