It is about the simulation of brag fiber grating.Using direct analytical method to determine the variation of reflectivity vs length curve

数学建模时常用的matlab编码，对建模中出现的问题很有效(Commonly used mathematical modeling matlab coding, modeling the problems in a very effective)

contrast adjusment Contrast is the difference in luminance or color that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view. Because the human visual system is more sensitive to contrast than absolute luminance, we can perceive the world similarly regardless of the huge changes in illumination over the day or place to place. The maximum contrast of an image is the contrast ratio or dynamic range

定义坐标轴的显示范围用axis指令 语法：axis([xmin xmax ymin ymax]) 你的例子ymin ymax应分别设为0和0.5，xmin xmax 取周期的两端。 然后再plot（x,y） 欢迎一起探讨matlab的使用：） (draw picture in matlab)
