一个用fortran90写成的BVP（ODE）的求解器，作者是写matlab函数bvp4c的作者。原理差不多。不过这个版本是用f90写的，运算速度更快。本包内含如何运这些程序的论文及算例，很好上手。(In the declarations part of this module, we first define the BVP_SOL type, which represents the numerical solution. We next define the interface BVP_INIT, which is overloaded to provide a number of functions for allowing the user to specify initial information for the computation, the interface BVP_EXTEND, which is overloaded to provide functions for extending the numerical solution to a new domain that are useful in the context of parameter continuation, and the interface BVP_EVAL, which is overloaded to provide a function for retrieving solution information. Next a number of global variables employed throughout the code are defined. )

加性噪声一般指热噪声、散弹噪声等，它们与信号的关系是相加，不管有没有信号，噪声都存在。而乘性噪声一般由信道不理想引起，它们与信号的关系是相乘，信号在它在，信号不在他也就不在。(The additive noise generally refers to the thermal noise, shot noise, which is added with the signal of the relationship, or no signal, noise are present. While the multiplicative noise in general by the channel caused by non ideal, they are multiplied by the signal, signal in it, the signal is not in him is not in.)
