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.

Face Recognition using wavelet transform in matlab

利用C、C＋＋或者MATLAB对一张照片进行DCT和DFT变换，并进行简要分析。 比较保留20个DCT变换系数重构的图像与原始图像之间的差别(Use C, C++ or MATLAB to carry out a photo on the DCT and the DFT transform, and a brief analysis. Comparison of retention of 20 DCT transform coefficients of image reconstruction with the difference between the original image)
