相位恢复算法
有会相位恢复算法的吗?能帮我看看下面的代码错哪儿了吗?不胜感激 z_=V6MDM J qmL|S) 2d centered Fourier transform,居中的傅里叶变换 4CtWEq %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Jl6lZd(Np % Citation for this code and algorithm: L4ct2|w}ul % Tatiana Latychevskaia and Hans-Werner Fink }:u-l3e % "Practical algorithms for simulation and reconstruction of digital in-line holograms", OOXP1L % Appl.
