直接序列扩频（Direct Sequence Spread Spectrum）工作方式，简称直扩方式（DS方式）。就是用高速率的扩频序列在发射端扩展信号的频谱，而在接收端用相同的扩频码序列进行解扩，把展开的扩频信号还原成原来的信号。(irect Sequence Spread Spectrum (Direct Sequence Spread Spectrum), hereinafter referred to as Direct expansion mode (DS). Is a high rate of spread spectrum sequence extension in signal spectrum, and at the receiving end with the same spread spectrum code sequence for expansion, the expansion of the spread spectrum signal back into the original signal. )

以Rosenbrock矩阵做为测试函数的微粒群算法的一些源码(Rosenbrock matrix in order to function as a test of the Particle Swarm Optimization of a number of source)

设计的带通滤波器方法 改变参数就行了 里面有几种方法(designed band pass filter change of parameters on a trip inside there are several ways)

Finds the roots of a function using the Newton method with line search

matlab编写的多示例多标记分类程序，采用miSVM算法，svm做分类器，其中附有各个调用函数，和作为例子的数据和主程序，可以运行，可以多多示例多标记样本进行分类。(matlab prepared multi-instance multi-label classification procedures, using miSVM algorithm, svm do classifier, which function with each call, and as an example of the data and the main program, you can run, you can sample a lot of examples of multi-label classification.)

这个是关于DIOPHANTINE方程的一个程序。只是一个函数文件。可以应用到你需要的主程序中，方程式是关于GPC预测控制中的方程。不是一般性方程(This is a program on Diophantine equations. Just a function file. Can be applied to the main program you need, the equation is the equation GPC predictive control. Not a general equation)
