pz
Do a pole / zero analysis
General form
pz node1 node2 node3 node4 ( CUR | VOL ) ( POL | ZER | PZ )
Do a pole-zero analysis of the current circuit, as a .PZ line would, and make its results the current plot. The arguments are the same as on the .PZ line: node1 and node2 are the input nodes and node3 and node4 the output nodes; CUR asks for the transfer function (output voltage)/(input current) and VOL for (output voltage)/(input voltage); POL, ZER and PZ find the poles, the zeros, or both.
Use print all to see the poles and zeros found.
Example
pz 1 0 3 0 CUR POL print all
