QR分解-householder reflection(householder reflection)

解方程例子，含有很多例子，弄到可不容易，提供参考(Examples of solving equations, containing many examples is not easy to get and provide information)

this is good reference code for design

采用L-M优化算法用以训练BP神经网络，使其能够拟合某一附加有白噪声的正弦样本数据。设计一个三层BP神经网络，其网络的隐含层神经元的激励函数为双曲正切型，输出层各神经元的激励函数为线性函数，隐含层有6个神经元(LM optimization algorithm used to train BP neural network to enable it to fit a white noise, sine additional sample data. Design a three BP neural network, its network of hidden layer neuron activation function of hyperbolic tangent type for the output layer activation function of each neuron is a linear function of the hidden layer has 6 neurons)

一部很经典的关于MATLAB的教材，内容很详细，不多说了，自己下载吧！(this is very good book,if you now study MATLAB,you must load it.)

提供粒子群算法的部分Matlab程序，在此基础上学习粒子群算法更方便、快捷。(Part of PSO algorithm provides Matlab program, in this based on particle swarm optimization learning more convenient and faster.)
