With this commit the patch provided by Alessio Cacchiatori the S-parameter is completed:
Noise simulation added with C matrix output
Y and Z matrix output enabled
To allow compiling with gcc, the dense.h inline functions have been put into denseinlines.h
Bug report due to Hartmut Henkel in
>> [Ngspice-users] Noise analysis depends on ac parameter
The noise analysis internally depends on an ac analysis
to derive "inoise" from "onoise"
("onoise" is multiplied with the inverse ac gain from input to output)
This AC analysis used all the given ac magnitudes for all vsrc/isrc
devices in the deck.
This fix overrides all ac magnitudes with zero,
except for the given input device,
whose magnitude is set to one.
