program about ecg data filter in matlab

基于四阶累积量的联合对角化，其中给出两种四阶累积量计算方法，方便理解。这个算法还是比较难的，可以参看下独立分量分析中的jade算法(Fourth-order cumulant-based joint diagonalization, which gives two fourth-order cumulant method, easy to understand. This algorithm is quite difficult, you can see under the jade independent component analysis algorithm)

通过一个简单实例说明三次样条插值法二维曲面法(plot surface by 3-spline interpolation method)

说明：  用NN算法对于急病类型进行分类实例 NN For Classification(NN algorithm used for the mistress type NN For example Classification Classification)

Zernikz descriptors: the similarity measure based on the descriptor should deliver a similarity ordering that is close to the application driven notion of resemblance.

ITD进行模态识别，得到模态参数,ITD 法是一种单输入多输出、基于包含系统参数的自由振动方程识别结构参数的方法，(ITD modal identification, get the modal parameters.ITD method is a single-input multiple-output, based on the structure of the free vibration equation parameters include system identification method parameters,)

在悬架matlab仿真中，求解加速度、悬架动挠度，轮胎动位移的功率谱密度(Suspension matlab simulation, solution acceleration, suspension deflections, tire displacement power spectral density )

image watermarking method

说明：  计算阶次分析的案例，需要转速信号进行角度域重采样。(In the case of order analysis, the angle domain resampling of speed signal is needed.)

三状态锁相环的matlab仿真程序，使用stateflow方法编译(Three state phase locked loop of matlab simulation program, use compiled stateflow method )
