WebDec 15, 2024 · Thus, we modify Prony’s method and use that p 0 ≠ 0 (instead of p m = 1) since we have assumed that 0 is not a zero of ρ m (all zeros lie in D α). Thus, we may renormalize ρ m so that p 0 becomes an arbitrary non zero value, e.g. p 0 ≔ 1 , which can be done by defining p ̃ ν ≔ p ν p 0 .
