Network.z

Impedance parameter matrix.

The z-matrix [1] is a 3-dimensional numpy.ndarray which has shape fxnxn, where f is frequency axis and n is number of ports. Note that indexing starts at 0, so z11 can be accessed by taking the slice z[:,0,0].

Returns :

z : complex numpy.ndarray of shape fxnxn

the Impedance parameter matrix.
