梯度下降法的matlab版本实例,带收敛轨迹图。(the steepest descent algorithm with matlab )

Variable step size Afine Projection, adaptive filter algorithm

自编的PSO算法，用于求解函数极值非常不错(Self of the PSO algorithm for solving the extreme value function is very good)

说明：  几个实用的程序 MATLAB查找素数的源程序代码。MATLAB创建无限循环的GIF动图。MATLAB求解拟合圆的圆心和半径。MATLAB实现改进的欧拉法求解常微分方程组。(Several practical programs)

指纹识别预处理.细线化处理，C++翻译过来MATLAB坐仿真处理，适合初学者学习(fingerprint matching)

I send the matlab code for image compression using embedded zero tree and set partitioning in hierarchial tree.Also i send matlab code for speech compression using rabiner algorithm and OFDM transceiver design.

hardware monitoring driver for the National Semiconductor PC87427 Super-I O chip.

说明：  各种各样的不同代码源打包，都是经过运行的，绝对可以使用。(A variety of different source code packages are run through, and absolutely can be used.)

扩频通信，从电磁波利用来看，与一般现有的常规通信方式完全不同。扩频通信利用伪随机编码把信息数据（窄带信号）的频谱进行扩展，形成宽带的低功率谱密度信号发射，使用不同的伪随机序列编码，不同通信用户可在同一频段、同一时间工作，互不影响或干扰极小地进行通信。(Spectrum, from the electromagnetic waves used term, and the general existing conventional means of communication is entirely different. Spread spectrum communication using pseudo-random code to the information data (narrowband signal) to extend the spectrum, the formation of low-power spectral density broadband signal transmission, using different pseudo-random sequence of coding, different communication users at the same frequency band, at the same time work, mutual does not affect or interfere with a very small way to communicate.)
