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 B*@0l: (rieg F 2d centered Fourier transform,居中的傅里叶变换 L^FQ|?* %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% I3.cy i % Citation for this code and algorithm: _'mK=`>u % Tatiana Latychevskaia and Hans-Werner Fink b Y2:g ) % "Practical algorithms for simulation and reconstruction of digital in-line holograms", 4=nh'
