利用遗传基因算法对SVM-RFE算法进行优化，从而获取更优异的特征，提高检测率，该算法的SVMtrain利用matlab自带的函数(The use of genetic algorithms to optimize the SVM-RFE algorithm, in order to gain more excellent features, improve the detection rate of the algorithm using matlab comes SVMtrain function)

利用迭代方法自动确定图像目标分割阈值。程序包内有matlab源程序，示例图片及运行结果比较。(Iterative method automatically determines the image object segmentation threshold. Matlab source code within the package, sample images, and operations were.)

一些个人收集的小波变换的程序，仅供学习参考，没有什么重要意义(Some of my personal collection of wavelet transform procedures for reference purposes only study, nothing of great significance)

C语言实现数字信号处理信号过系统（FIR、IIR型滤波器，含画图子函数。） 需：include"graphcis"(C-signals over the digital signal processing systems (FIR, IIR filters, including drawing subroutine.) Must: include " graphcis" )

光脉冲在光纤中传输时受到二阶色散作用，求解二阶色散方法(pulses in optical fiber transmission by the second-order dispersion role for second-order dispersion methods)

二阶粒子群，比pso更加精确更加灵敏地优化函数。在标准pso算法中，微粒的飞行速度仅仅是微粒当前位置的函数，而二阶粒子群算法中微粒飞行速度的变化与微粒位置的变化有关(Second swarm, more sensitive and more accurate than pso optimize function. Pso algorithm in the standard, the particle particle flight speed is only a function of the current position, the second particle swarm flying speed of particles in the particle changes related to changes in the position)

基于matlab GUI的一个简单计算机系统，能实现加减乘除等简单算法(A simple matlab GUI based computer system, to achieve a simple algorithm for addition, subtraction, etc.)

this file have simple demodulation program for qpsk demodulation. it will give the bit of stream after demodulation of qpsk (quadrature phase shift keying) wave.

对采样率进行变换，通过插入零，然后再做低通滤波，实现采样率的提高(Change the sampling rate by inserting zeros, and then do a low pass filter, the sampling rate to achieve the improvement of)
