非线性方程的几种数值解法的matlab例程，pdf格式，欢迎指教！(Nonlinear equations in several numerical method of matlab routines, pdf format, welcome the advice!)

student-t function, this function is used on the field of computer vision and machines learning

使用matlab画的半对数坐标纸（两种图纸）(Use matlab painting semi-logarithmic coordinate paper (two drawings))

this is PSO algorithm code that integrated with PID controller. This code example has been used for ASP system.

人工鱼群算法是李晓磊等人于2002年在动物群体智能行为研究的基础上提出的一种新型方盛优化算法，该算法根据水域中鱼生存数目最多的地方就是本水域中富含营养物质最多的地方这一特点来模拟鱼群的觅食行为而实现寻优。算法主要利用鱼的三大基本行为：觅食、聚群和追尾行为，采用自上而下的寻优模式从构造个体的底层行为开始，通过鱼群中各个体的局部寻优，达到全局最优值在群体中凸显出来的目的。 这是一个鱼群算法的案例，希望大家可以有所收获(Artificial fish swarm algorithm is a new fangsheng optimization algorithm proposed by li xiaolei et al. on the basis of the research on intelligent behavior of animals in 2002. This algorithm simulates the foraging behavior of fish swarm according to the characteristics that the place with the largest number of fish survival is the place with the largest number of nutrients in the water area.)

二用户CDMA系统，信道为加性高斯信道，使用BPSK调制，15位M序列扩频，可以正确解扩解调。 输出为2用户的基带信号、扩频信号、PSK调制信号、解调信号的时域和频域特性，给出两个用户分别的误码率。 (Second, the user CDMA system, channel for the additive Gaussian channel, using BPSK modulation, 15 M Sequence Spread Spectrum, you can correct demodulation despreading. Output of 2 user' s baseband signal, spread spectrum signal, PSK signal modulation, demodulation signal time domain and frequency domain characteristics of the two users are given the bit error rate, respectively.)
