c陷井与缺陷 我自己感觉很不错的一本书 里面的问题很经典(c traps and defects I feel very good in a book inside the problem is very classic)

日期转换的程序。可将字符型日期转换为数值型。增加了一种常用日期编码格式。建议将其作为mex使用，速度有显著提高。(Date conversion process. Date can be converted to a numeric character. Added a common date code format. Recommend its use as a mex, the speed has improved significantly.)

说明：  利用反步法设计的控制律，进行轨迹跟踪仿真。(Using the control law designed by backstepping, the trajectory tracking simulation is carried out.)

matlab code for coaxial modes

旅转机械故障机理及诊断方面的专业书籍，是全面掌握机械故障诊断很全面的方面的书(Journey to the mechanism of mechanical failure and diagnostics, professional books, is a comprehensive diagnosis of mechanical failure have very comprehensive books)

Matlab 命令总结 散点图 一元线性回归 多元线性回归 非线性回归 其它命令(Matlab command scatter summed up one linear regression multiple linear regression non-linear regression of other orders)

e-book for engineering

说明：  该程序用于联合傅里叶变换，辅助联合傅里叶变换光学实验的分析(JoinTransformCorrelator)

说明：  采用频率调制 为1000Ｈｚ的载波，在解调前把加性白高斯噪声加入到调制信号。当噪声功率和调制信号功率比为０.００１，０.０１，０.０５，０.１和０.３是进行解调并绘出调制信号(The use of frequency modulation for the 1000Hz carrier, in the demodulation before AWGN added to the modulation signal. When the noise power and modulation signal power ratio of 0.3 is 0.001,0.01,0.05,0.1 and demodulation and modulation signals mapped)

说明：  牛顿均差插值公式，使用各阶均差，比拉格朗日插值计算量省(Newton interpolation formula are poor, the use of the bands are worse than the Lagrange interpolation calculation of the volume of the province)
