[Qucs-help] two ports in equation block

[Chuck M. <cmc...@hr...>]

I'm trying to de-embed a transistor.  I would like to read in 3 sets of
two port s-parameters.  S-dut, S-pads-open, S-pads-short.
Then 
1) S_dut -> Y_dut,
2) S_open->Y_open,
3) Y_dut1 = Y_dut - Y_open,
4) Y_dut1 -> Z_dut1,
5) S_short -> Z_short
6) Z_dut_intrinsic = Z_dut1 - Z_short
7) S_dut_intrinsic -> S_naked 

Look at the nice transistor without parasitic pads

It looks to me like I have only one set of S-matrix during simulation
time.  m=eye(2) will create a new matrix but I don't know how to assign
m[1,1]=S[1,1] 
will not work.  as the L-value sub-scripting doesn't seem to be
accepted.
thanks
