一种改进的LMS算法及其在噪声对消中的应用。在分析传统定步长LMS算法和变步长LMS算法的基础上，提出了一种改进的变步长LMS算法。新算法利用瞬时误差绝对值三次方的指数形式和遗忘因子同时调整步长，更好的解决了收敛速度和稳态误差的矛盾(An improved LMS algorithm and its application in noise cancellation. In the analysis of the traditional fixed step and variable step size LMS algorithm based on LMS algorithm, a modified variable step size LMS algorithm. Absolute value of the new algorithm uses the instantaneous error and the form of cubic exponential forgetting factor while adjusting step, a better solution to the convergence speed and steady-state error of the contradictions)

it s a camera calibration code written with matlab, and it s very useful for visual manipulation.

马斯京根法洪水演算，分顺演和反演，有区间来水和无区间来水，可用于学习Matlab和洪水演算(Mas Beijing flood routing root method, points along the play and inversion, with and without reaches, reaches can be used to learn Matlab and flood routing)

Blind signal seperation method using maximum likelyhood method

改进根升余弦成型滤波，信噪比可达-70dB，性能较标准升余弦提高较大，在TVB2脉冲成型中仿真验证过(Improved root raised cosine shaping filter, SNR up to-70dB, performance than the standard raised cosine larger increase in pulse shaping TVB2 verified in simulation)

The NCT includes 4 External validity indices and 8 internal validity indices, and the sub-routine validity_Index.m is designed to use them. This tool is suitable for the research work such as the performance comparison of different indices on estimation of the number of clusters, algorithm design by improving part codes of this toolbox. i) External validity indices when true class labels are known: Rand index Adjusted Rand index Mirkin index Hubert index ii) Internal validity indices when true class labels are unknown: Silhouette Davies-Bouldin Calinski-Harabasz Krzanowski-Lai Hartigan weighted inter- to intra-cluster ratio Homogeneity Separation iii) Others Error rate (compared with true labels) System Evolution: it is used to estimate the number of clusters and give separable degrees between clusters.

基于MATLAB的PCA和KPCA的实现，有图，有返回的参数，绝对可以运行！(Based on the PCA and KPCA MATLAB to achieve, there are plans to return to the parameters, the absolute can run!)

说明：  在matlab里多普勒信号是怎么表示的,求一维非均匀采样信号的频谱(In matlab how Liduopule signal is expressed in seeking one-dimensional non-uniform sampling frequency spectrum)

自己编写的锁模激光器原理模拟，很简单有助于理解锁模激光脉冲的性质。(I have written a mode-locked laser simulation principle is very simple to help understand the nature of mode-locked laser pulses.)
