简单的随机共振仿真程序代码，适合初学者，包含龙格库塔法解郎之万方程(Simple stochastic resonance simulation code, suitable for beginners, practical, better effect.)

利用传输矩阵法对相移光纤光栅的反射及透射谱进行了仿真，由于光栅的相移具有一般性，因此在本文中将光栅分为两部分，第一部分为未引进相移的均匀布拉格光栅，第二部分为引入了相移的均匀布拉格光栅(The transmission matrix method is used to simulate the reflection and transmission spectrum of phase shifting fiber Bragg grating. Because the phase shift of the grating is general, the grating is divided into two parts in this paper. The first part is the uniform Prague grating without the introduction of phase shift, and the second part is a homogeneous Prague grating with phase shift.)
