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 +=MO6}5T g4d5G=y 2d centered Fourier transform,居中的傅里叶变换 7(~^6Ql! %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% V/|Ln*rm % Citation for this code and algorithm: p&_a kQj % Tatiana Latychevskaia and Hans-Werner Fink v>g1\yIw % "Practical algorithms for simulation and reconstruction of digital in-line holograms", Ih`n:aA % Appl.
