matlab从入门到精通，讲解了matlab 的基础知识(matlab from entry to the master，Explained the basics of matlab)

matlab中的标准svm程序源码，用于解决线性的回归问题，不能用于解决非线性，区别于最小二乘支持向量机。(svm program source code, standard Matlab is used to solve linear regression problems, can not be used to solve nonlinear, different from the least squares support vector machine.)

提取原始信号的功率谱就可以看出在哪个频带的能量比较高，噪声主要集中在哪里，这样就可以专门分析那个频带的噪声(The power extracted the spectrum of the original signal can be seen in which frequency band energy is high, the noise is mainly concentrated in where, so that it can be devoted to the analysis of the frequency band of noise)

大间隔最近邻居（Large margin nearest neighbor (LMNN)）分类算法是统计学的一种机器学习算法。该算法是在k近邻分类其中学习一种欧式距离度量函数。(Spaced nearest neighbor (Large margin nearest neighbor (LMNN)) classification algorithm is a statistical machine learning algorithms. The algorithm is learning a Euclidean distance metric function where k nearest neighbor classification.)

串联式混合动力电动汽车的能量控制策略，恒温控制策略，当电池SOC在合适范围内依靠电机驱动，发动机关闭与否取决于汽车行驶所需要的能量。低于SOC下限时，依靠发动机驱动，多余能量为蓄电池充电。高于上限时关闭发动机依靠电机驱动。((Series Hybrid Electric Vehicle Control Strategy of energy, constant temperature control strategy, when the battery SOC at the right to rely on the scope of motor drive, the engine shut down or not depends on the car of the energy needed. SOC is lower than under the limit, relying on the engine-driven, extra energy for battery charging. Higher than the upper limit of the closure of the engine relies on motor drive.))

用matlab实现了OFDMQPSK的调制和解调过程,能很好地实现QPSK的调制解调过程。(OFDMQPSK realized by matlab modulation and demodulation process, can well realize the QPSK modulation and demodulation process.)

这是自己写的一个 数字信号发生器 ，里面包含几个界面，包括了 电子琴、电话机按键、信号合成等，可以声卡发生，请参考！(This is to write a digital signal generator, which contains several interfaces, including keyboard, telephone keypad, signal synthesis, can sound occurred, please refer to!)

Particle swarm optimization algorithm ( 粒子群优化算法)

波束形成方法的到达方向估计。波束成形，是通用信号处理技术，用于控制传播的方向和射频信号的接收。作为Wi-Fi802.11n标准的可选部分，beamforming被定义为两种基本类型：内在的和外在的。(The Beamforming method for direction of arrival estimation)

主要描述Matlab优化实例。主要包括线性规划问题、foptions函数、非线性规划问题、“半无限”有约束的多元函数最优解、极小化极大（Minmax）问题、多目标规划问题、最小二乘最优问题和非线性方程(组)求解。 (The main description Matlab optimization instance. Mainly include linear programming problem, function foptions, nonlinear programming problem, " a semi-infinite constrained multi-function optimal solution, minimization great (MinMax), a multi-objective programming problems, least squares optimization problem and non- linear equation (group) to solve.)
