DIRECT全局优化—无约束，基于MATLAB编制，可直接编译(DIRECT global optimization- non-binding, based on MATLAB preparation, can be directly compiled)

This is a MATLAB based program that computes the weights and beamforming pattern of a: I. Linear array II. Rectangular planar array

说明：  基于HSM（harmonic-to-subharmonic）的基音提取算法。本算法通过对HSM建模，消除了基音提取过程中基音减半或增倍的现象，大大提高了准确性能。(Based on HSM (harmonic-to-subharmonic) of the pitch extraction algorithm. HSM model by the algorithm, the extraction process to eliminate the pitch halving or pitch doubling phenomenon, greatly improving the accuracy of performance.)

说明：  在神经网络中用求协方差矩阵的方法对人脸图像进行压缩及恢复(In the neural network covariance matrix using the method of face image compression and restoration)

反馈控制系统设计与分析－MATLAB语言应用（薛定宇）(Feedback Control System Design and Analysis-MATLAB language applications (Xue Dingyu))

随机数生成的matlab程序，可作为数值分析等的学习工具。(Matlab program, the random number generator can be used as a learning tool of numerical analysis .)

通常情况下是线性的分类,但在复杂情况下,要把他转换到另一空间来,以便线性的分类, SVM有其优势,还能做非线性的波束形成.(under normal circumstances is linear classification, but in complex situations, it is necessary to change his room to another, to the linear classification, SVM has its advantages, the ability to do nonlinear beam forming.)

该程序用于解决光学领域金属介质膜参数的问题，运行速度快。(The procedures for the settlement of the optical field of metal dielectric film parameter problem, fast running speed.)

说明：  利用CMA算法实现4QAM信号的盲均衡，步长0.001，SNR=15，取得了较好的结果。没有实现相位补偿(Using the CMA algorithm to achieve blind equalization of 4QAM signals, with a step size of 0.001 and SNR = 15, good results have been achieved. No phase compensation)
