对输入的数字图像进行二维离散傅立叶变换，由matlab实现(The input digital image to two-dimensional Discrete Fourier Transform, from matlab realize)

说明：  function [ret,x0,str,ts,xts]=s4(t,x,u,flag) s4 is the M-file description of the SIMULINK system named s4. The block-diagram can be displayed by typing: s4. SYS=s4(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.

阵列天线中方向图波束，方向性系数，半功率波瓣宽度等相关性能参数的计算仿真(Beam array antenna pattern, directivity, half power beam width and other related performance parameters of computer simulation)

这是用实施镶边效果这是一个分数延迟线，作为构建块。基本上镶边效果延迟实现不同时间acording一个低频控制信号。(This is the implementation of the flanger effect is a fraction of the delay line, as building blocks. Basically, the flanger effect delay to different time acording to a low-frequency control signal.)

基于simulink的现代通信系统仿真。很好的仿真源码！ ( Simulink-based simulation of modern communication systems. A good source of simulation! )
