改进人工神经网络法

说明：  matlab下实现拉格朗日插值与三次样条插值，附实验报告(Lagrange interpolation matlab to achieve with cubic spline interpolation, with a lab report)

光子晶体点缺陷程序，特别是做光子晶体缺陷的同行，可以借鉴一下。(Photonic crystal point defect procedures, especially peers to do the photonic crystal defects, can learn.)

k-means clustering : Pattern Recognition

Testing complicated str.replace.

说明：  change raw and column of matrix

传输矩阵法求一维光子晶体的特性，包括透射谱，反射谱(Transfer matrix method the characteristics of one-dimensional photonic crystal, including the transmission spectra, reflection spectra)

With this document, is intended to show some manipulation of signal processing techniques regarding continue and discrete signals, odd and even components, and periodic discreet signal, showing the mathematical part and the source code in Matlab on which it’s possible to try it out.

说明：  使用交互式多模型技术，滤波器选择无迹卡尔曼滤波器。(We use ukf to achieve imm successfully)

说明：  两个序列的互相关函数的归一化运算。 先生成两个序列，再调用。(cross-correlation function)

基于Matlab的边缘检测的研究以及各种算子的对比。(Matlab edge detection based on the research and a variety of comparison operators.)
