最优化共轭梯度算法、最速下降法、牛顿法、拟牛顿法matlab源码，含泪奉上(Conjugate gradient optimization algorithm, the steepest descent method, Newton method, quasi Newton method matlab source, tears offer)

精通Matlab7.0（北航 张志勇），适合Matlab初学者(Proficient Matlab7.0 (Northern Zhang Zhiyong), suitable for beginners Matlab)

该算法基本思想是利用一组带有相应权值的随机样本即粒子去逼近PHD分布和基数分布，其意义在于不仅解决重积分计算没有闭式解的难题，而且在滤波过程中，PHD函数被一系列离散的带权值的样本近似，随着样本粒子数量的增加，PHDF接近于Bayes最优估计，而且不受模型线性和高斯假设的限制，可以适用于非线性非高斯的随机系统。(The algorithm the basic idea is to use a set of random sample with the corresponding weight namely particle approximation PHD and base distribution, its significance lies in not only solve the problem of multiple integral calculation without closed solution, and in the process of filtering, PHD function by a series of discrete weighted value of sample approximation, with the increase of sample particles, PHDF close to the Bayes optimal estimation, and is not subject to the assumptions of the linear and gaussian model can be applied to nonlinear non-gaussian stochastic system.)

说明：  用于波束成形的matlab代码，主要思想是用DFT码本实现(A large number of antennas are arranged at the base station of the system, and then the signals from different directions are weighted by beamforming preprocessing. After that, the power of each signal can be concentrated in a certain beam space for transmission,)
