When I tried to find input impedance function's pole zero of a parallel LC network using Multisim
pole zero analysis, I get following message
"
...........

| | doAnalyses: matrix is singular

| | pz simulation(s) aborted "

The circuit as well as log file attached.

How to correctly perform pole zero analysis?

The answer is given by the program: The lossless LC tank creates a singularity. To be realistic you must add some losses.
