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 [{!j9E?( OXCml(>{ 2d centered Fourier transform,居中的傅里叶变换 Ai_|) %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% dgqJ=+z 0y % Citation for this code and algorithm: 2Z9gOd<M~ % Tatiana Latychevskaia and Hans-Werner Fink X|n[9h:% % "Practical algorithms for simulation and reconstruction of digital in-line holograms", 2] wf`9ZH % Appl.
