最近邻插值,在图像处理中，对变换后的图像进行插值(Nearest Neighbour interpolating)

％96年中国大学生数学建模竞赛B题:洗衣机(96% of university students in China Mathematical Contest in Modeling B theme : Washing Machine)

对文件夹中的文件自动编号或恢复为旧文件名。当然，经过小的修改，也可完成其他批量修改文件名的功能，如批量修改后缀名等等。利用MATLAB的GUI技术，做了个界面，方便用户使用(Automatic numbering files in the folder or revert to the old file name. Of course, after minor modifications, to be completed by the functions of the other batch change file names, such as batch modify the extension. MATLAB GUI technology, made the interface, user-friendly)

自适应噪声抵消算法,一种补偿抵消的算法，即在检测有用信号的同时，专设一个传感器检测干扰噪声，再从检测信号中减去噪声传感器的输出，以抵消叠加在有用信号上的干扰噪声。(Adaptive noise cancellation algorithm)

互补滤波，应用在INS和磁罗盘融合姿态解算，详细说明(Complementary filtering, application integration attitude in solving INS and magnetic compass, a detailed description)

牛顿迭代法求无约束一维极值问题的速度相当快，而且还有一个好处就是能高度逼近最优值。(Newton iteration method for one-dimensional unconstrained extremum problem very fast, but there is a benefit that can be highly close to the optimal value.)

用matlab写的一个正交匹配追踪基的函数程序(Written by matlab function program a group of orthogonal matching pursuit)

说明：  对于一个时间序列，通过奇异谱分析，实现去噪和平滑(realizing SSA for time series)

matlab 中基于互相关函数的程序，希望对各位学者有帮助！(matlab cross correlation function based on the procedure, in the hope that scholars will help you!)

使用mantlab，计算图像的一阶熵和二阶熵(computer the first-order entropy and the second-order entropy)
