牛顿拉夫森法用来解决极大似然估计的问题。很好用。(Newton La Fusen method to solve the problem of maximum likelihood estimation. Good use.)

thanx u gav me a nice option to upload and take models

用matlab实现iris数据分类，适合初学者的一个很有用的算法(Using matlab to achieve iris data classification, suitable for beginners of a useful algorithm)

主要编写了生活中几个常用的函数：二次函数、分段函数。(Mainly to write several commonly used functions in life, quadratic function, piecewise function.)

关于matlab的几个实例和若干教程，国外写的(Several instances of matlab and tutorial written abroad)

自组织特征映射模型(Self-Organizing feature Map)，认为一个神经网络接受外界输入模式时，将会分为不同的区域，各区域对输入模式具有不同的响应特征，同时这一过程是自动完成的。各神经元的连接权值具有一定的分布。最邻近的神经元互相刺激，而较远的神经元则相互抑制，更远一些的则具有较弱的刺激作用。自组织特征映射法是一种无教师的聚类方法。(Self-organizing maps model (Self-Organizing feature Map), that a neural network to accept outside input mode, will be divided into different regions, the regional input modes have different response characteristics, while the process is done automatically . The connection weights of neurons with a certain distribution. Nearest neurons stimulate each other, while distant neurons are mutually inhibitory, with a further some of the weaker stimulus. Self-organizing feature map method is a clustering method without teachers.)
