MATLAB demo for phase retrieval using Perturbed Amplitude Flow algorithm, which is proposed by B. Gao et al in 2020 [1].
- Complex-numebr case (m/n=5)
- Real-number case (m/n=5)
For detailed peformance comparison with other non-convex algorithms like AF, TAF, RAF, in terms of the relative error progress curve with or without noise, recovery probability at various sampling rates m/n, please see the paper [1].
