scipy.signal.unique_roots

scipy.signal.unique_roots(p, tol=0.001, rtype='min')

Determine the unique roots and their multiplicities in two lists

Inputs:

p – The list of roots tol — The tolerance for two roots to be considered equal. rtype — How to determine the returned root from the close

ones: ‘max’: pick the maximum

‘min’: pick the minimum ‘avg’: average roots

Outputs: (pout, mult)

pout – The list of sorted roots mult – The multiplicity of each root
