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. )
