Matlab中erf(x)函数的表达式是怎样的，erf(x)与标准正态分布函数之间的关系是怎样的，怎样自己编制一个计算标准正态分布函数数值近似值的函数，如何利用matlab自带的erf(x)函数包近似计算标准正态分布函数的值，数值计算值与用erf(x)转化求得的值之间的相对误差是怎样的。(将中文译成英语 Matlab, erf (x) function expression is what, erf (x) the standard normal distribution function and the relationship between what and how to prepare their own calculation of the standard normal distribution function a value function approximation, how to use matlab comes with erf (x) function package approximate standard normal distribution function values??, numerical values ??and with erf (x) between the values ??obtained into the relative error is like. )

支持向量机方法，用matlab实现，用于分类(Support Vector Machine method, using matlab realize for classification)

山上有m只猴子要选大王,选举办法如下：所有猴子从1到m进行编号并围坐一圈,从第一号开始按顺序1,2,...n继续报数,凡是报n号的猴子都退出到圈外,照此循环报数,直到圈内只剩下一只猴子时,这只猴子就是大王.输出大王的编号。 (Mountains have m of the monkeys to elect king, method of election are as follows: All monkeys are numbered from 1 to m, and sitting around a circle, to begin from the first order 1,2, ... n continue to report the number of those who reported that n No. The monkeys are out to outsiders the basis of this report the number of cycles until the circle only one monkey, the monkey is king. Output King number.)
