SIFT

此文档涵盖了Matlab初学者和有一定基础的学者，在编程过程中遇到的指令方面的集合。(This document covers the Matlab have a certain foundation for beginners and scholars, in the programming process encountered in a collection of directives.)

设计卫星绕地球运动的图象。要求：地球的直径≥5cm，卫星用五角星表示，卫星轨迹呈椭圆其中一部分轨迹被地球遮挡。(Design of the satellite around the earth in the image. Requirements: Earth' s diameter ≥ 5cm, with a five-pointed star, said the satellite, the satellite orbit was elliptical orbit by the Earth blocking part.)

基于遗传算法的以最小二乘法为准则条件下的电动汽车与内燃汽车的成本对比(Cost comparison based on genetic algorithm, the least squares method for the guidelines under the conditions of electric vehicles with internal combustion automobile)

通过改进的阈值函数，实现小波阈值去噪，通过验证，效果较好(Improved threshold function, the wavelet threshold denoising pass validation, the better)

说明：  MATLAB在信号处理中的典型应用-MATLAB在傅里叶变换中的应用。(MATLAB in signal processing in a typical application-MATLAB in the Fourier transform applications.)

1、本程序用于仿真里德-穆勒（Reed-Muller）码在AWGN信道中的性能，调制采用bpsk 2、理论请参见《差错控制编码》（第二版），Shu Lin（美）编，晏坚等（译）一书P70-75.且仿真结果与书中图4-2完全一致 3、BPSK_AWGN_RM_Code.m为主程序，点击运行即可 4、The_creation_of_RM_code.m和RM_Decode.m分别为RM码的编、译码程序，而Majority_logic_decision.m用于译码中的大数判决，combine_dunction.m用于计算组合数。(1, the procedure for the simulation Reed- Muller (Reed-Muller) codes in AWGN channel performance, modulation using bpsk 2, theory, see " Error Control Coding" (second edition), Shu Lin (America) series , Yan Jian, etc. (translated) book P70-75., and the simulation results consistent with the book Figure 4-2 3, BPSK_AWGN_RM_Code.m-based program, click Run to 4, The_creation_of_RM_code.m and RM_Decode.m were RM compiled code decoding process, and in large numbers for decoding Majority_logic_decision.m judgment, combine_dunction.m used to calculate the number of combinations.)
