用Lax-Friedrichs及Courant-Isaacson-Rees格式求解一阶双曲型方程。(With the Lax-Friedrichs and the Courant-Isaacson-Rees format for solving first order hyperbolic equation.)

FEP算法，测试23个测试程序(参考姚新论文)(FEP algorithm,we can use it to test 23 testing procedures)

包含了小波去噪，BP,NLMS,LMS,RLS等去噪方法，效果不错。(It contains the wavelet de-noising, BP, NLMS, LMS, RLS and other denoising method, good results.)

matlab做的飞行仿真，是学习仿真很好的资料。(matlab flight simulation to do is to learn a good simulation data.)

This code realize the root_music algorithm

IRLS不等距时窗,用于多次波自适应减去过程中，更加准确的处理(this is IRLS code)

合成孔径雷达成像 算法与实现光盘数据及处理步骤(digital processing of SAR)

说明：  此程序是基于自适应限定记忆最小二乘法，运用递推算法。(This program is limited to memory based on adaptive least squares method, the use of recursive algorithms.)

Libelas(大规模高效立体匹配库)是cross-platfrom c++ 图书馆与MATLAB计算包装差异大的地图图像。输入 是一双纠正灰度立体图像的大小相同。输出相应的 差距的地图。(Libelas (LIBrary for Efficient LArge-scale Stereo matching) is a cross-platfrom C++ library with MATLAB wrappers for computing disparity maps of large images. Input is a rectified greyscale stereo image pair of same size. Output are the corresponding disparity maps.)

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.
