语音降噪 减谱法 是一个子程序 用与dsp语音降噪(noise reduce)

说明：  运用各种机器学习算法，检测人脸是否为照片(Various machine learning algorithms are used to detect whether a face is a photo)

说明：  蚁群算法的matlab源码,包括简单的输入，变量数，目标函数等，最后求得目标的最优解。(Ant colony matlab source code, including the simple input, the number of variables, objective function and so on, the final goal of the optimal solution obtained.)

说明：  仿真一个瑞利衰落信道的信道冲激响应，横坐标是信道采样阶数，纵坐标是对应采样阶数的幅值.(Simulation of a Rayleigh fading channel the channel impulse response, the abscissa is the order of channel sampling, corresponding ordinate is the amplitude of the order of sampling.)

利用电磁场的源激发方法来计算光子晶体波导例如光子晶体光纤，金属波导，表面等离子体波导等的传播特性比如传播常数以及束缚损耗，模场分布等，是一款极好的计算程序！(use of the electromagnetic field source excitation method was used to calculate the photonic crystal waveguide such as photonic crystal fibers, metal waveguide, Surface plasmon waveguide propagation, etc. For example, the propagation constants of shackles worn, mode field distribution, A is an excellent program!)

说明：  建立GEO和LEO的轨道，并计算他们间方位角和俯仰角速度及加速度，多普勒频移等重要参数。(established GEO and LEO orbits, and calculate their azimuth and pitch between angular velocity and acceleration, Doppler frequency shift and other important parameters.)
