创建裂纹

扩展卡尔曼滤波的matlab实现，doc格式的，挺好用的，大家可以试下。(ekf is erealised by matlab,it is very good. every can have a try.)

这是matlab的50道练习题，可以方便初学者进行自我检测，基本上这些题会做，matlab也就没有多大问题了。(This is a matlab 50 exercises, beginners can easily be self-testing, basically these questions will do, matlab there is no big problem.)

BP神经网络用于函数拟合与模式识别，能量谱分析计算,利用贝叶斯原理估计混合logit模型的参数。( BP neural network function fitting and pattern recognition, Energy spectrum analysis and calculation, Bayesian parameter estimation principle mixed logit model.)

该仿真为MATLAB仿真，关于充电桩的仿真，简单，可以运行(it is model on charging system ，it is simple and easy to understang.)

变步长的最小均方算法，步长可变，性能好，收敛速度快。(Variable step least mean square algorithm,have fast convergence rate.)

地震资料数字处理的首要环节，读取地震数据，以及地震记录的道头卷头信息(reads a SEG-Y file and outputs a seismic structure)

matlab编写的Hausdorff距离程序(Hausdorff distance program written in matlab)

自动识别图像中的圆形，并计算半径，及其相似度，希望有所帮助(Automatic identification of image circle, and calculate the radius, and its similarity, Hope that helps)

样本熵是时间复杂度的一个，度量是衡量时间序列复杂度的一个参数(The sample entropy time complexity metric is a parameter of the measure of time series complexity)

说明：  雷达对导弹进行测距，导弹受气流扰动同时雷达观测存在观测误差，通过卡尔曼滤波对导弹距离进行估计(Radar is used to measure the range of missile. The missile is disturbed by airflow and there is observation error in radar observation. Kalman filter is used to estimate the range of missile.)
