This code is an implementation of SURF (Speeded Up Robust Features). SURF will detect landmark points in an image, and describe the points by a vector which is robust against (a little bit) rotation,scaling and noise. It can be used in the same way as SIFT (Scale-invariant feature transform) which is patented. Thus to align (register) two or more images based on corresponding points.

This is a matlab simulation for CPM which is using viterbi decoder to decode the signal. There is pulse shaping used in this file and the default signal is assumed to be rectangukar

本书以MATLAB7.0中的小波分析工具箱为蓝本，结合工程实际中的各应用领域，讲解了如何应用MATLab来实现小波分析(MATLAB7.0 in this book to the wavelet analysis toolbox modeled, combined with engineering practice in various applications, explain how to apply MATLAB to realize Wavelet Analysis)

利用计算机编程实现加性干扰信号的维纳滤波(Use of computer programming plus interference signal Wiener filter)

一个按照时间抽取的基2快速傅里叶变换（基2FFT-DIT）。输入倒位序，输出自然顺序。(A time taken by the base 2 fast Fourier transform (base 2FFT-DIT). Enter the inversion sequence, the output of natural order.)

Simulation of the Logistic map n is the number of the simulated points. x is the simulated time series. a is the parameter.

本代码是容量限制交通分配的代码。但是不通过完整的OD表进行配流，而是针对组成OD表的逐一起始点、终点的基础数据进行配流。路权是取的BFR函数，加了距离惩罚函数。(This code is the capacity limit traffic assignment code. But not through the complete OD table assignment, but for each table consisting OD initial, end with the underlying data stream. Right of way is to take the BFR functions, plus a distance penalty function.)

采用符号计算法求一个周期内连续时间函数的三角级数展开系数,并绘出前七次(Using symbolic computation method for a period of continuous function of time Fourier series expansion coefficients, and draw seven times before )

the attached utility is a work I ve submitted to the university It shows what a jpeg compression is all about. the function implements the DCT transform, using a matrix operator. note that matlab has a function for the DCT and iDCT transforms that might be more efficient.(the attached utility is a work I ve submitted to the universityIt shows what a jpeg compression is all about.the function implements the DCT transform, using a matrix operator.note that matlab has a function for the DCT and iDCT transforms that might be more efficient .)
