1.分别在两个图中画出δ(n)和δ(n-2)，其中-10≤n≤10，画出U（n）其中-10≤n≤10。 2.分别在两个图中画出x1(n)=cos(2π×20×0.01×n)，0≤n≤10和x2(n)=(0.8)n，1≤n≤6。 3.由上一题，计算y(n)=x1(n)+x2(n)，并画图。(1. Draw the figure at two δ (n) and δ (n-2), where-10 ≤ n ≤ 10, draw the U (n) where-10 ≤ n ≤ 10. 2. Respectively in the two Draw the figure x1 (n) = cos (2π × 20 × 0.01 × n), 0 ≤ n ≤ 10 and x2 (n) = (0.8) n, 1 ≤ n ≤ 6. 3. from the previous question, calculate y (n) = x1 (n)+ x2 (n), and drawing.)

计算非线性光纤中的主导方程，非线性薛定谔方程的数值代码。(This is a code to solve the nonlineared Schrodinger equation numerically, which is the govenning equation in a nonlieared optical fiber.)

说明：  DSTBC源码，均可以运行成功，对于在研究DSTBC的朋友会很有帮助，我也希望我能得到其他朋友的帮助，站长手下留情，(DSTBC source can run successfully for the study would be helpful DSTBC friends, I also hope that my other friends can get help, head lenient,)

该函数实现的是激光光斑中心检测。首先对光斑进行预处理，然后利用灰度重心法来计算得到光斑的中心坐标,最后利用MATLAB的绘图功能描绘出光斑中心位置的变化情况。(This function is implemented in the laser spot detection. First spot pretreatment, and then use the barycenter method to calculate the coordinates of the center of the spot, the final use of MATLAB graphics depict the changes in the spot center position.)

这是模式分类一书中第五章中的基本感知算法的matlab代码。很有价值！(This is the pattern classification in chapter V of the book' s basic perception algorithm matlab code. Great value!)
