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 //Ai.Q.J[ @/UfDye 2d centered Fourier transform,居中的傅里叶变换 %PJhy 2 %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% htP|3 B % Citation for this code and algorithm: oVCmI"' % Tatiana Latychevskaia and Hans-Werner Fink UofTll) % "Practical algorithms for simulation and reconstruction of digital in-line holograms", (Vg}Hh?p % Appl.
