extern的用法，本文较详细的介绍了extern的用法及注意事项。(extern usage, this paper describes in detail the usage of extern and precautions.)

（一）目的：通过对常用的概率密度函数和分布函数的应用，达到熟练掌握概率密度函数和分布函数调用方法的目的。 （二）任务：对实际的案例进行分析，调用相应概率密度函数和分布函数，使用MATLAB软件计算其结果。 （三）要求：理解概率密度函数和分布函数，能够解决实际问题。 ((A) Purpose: used by the probability density function and distribution function of the application, to master the probability density function and distribution methods of the purpose of function call. (B) tasks: the actual analysis of the case, call the corresponding probability density function and distribution function, the use of MATLAB software to calculate their results. (C) requirements: understanding of the probability density function and distribution function, to solve practical problems.)
