一个emd分解程序，包括瞬时频率，瞬时幅值，边际谱，Hilbert谱(A emd decomposition process, including instantaneous frequency, instantaneous amplitude, the marginal spectrum, Hilbert spectrum)

求解TSP问题，即在N个城市中各经历一次回到出发点，使所经过的路程最短。采用连续的Hopfield网络实现以5个城市为例的TSP问题。(TSP problem, that each of the N cities experiencing a return to the starting point, so that the shortest distance elapsed. Use continuous Hopfield networks to five cities as an example of the TSP.)

用Matlab进行曲面的插值和拟合，来进行数值优化(Matlab surface interpolation and fitting, for numerical optimization)

灰色系统理论是研究解决灰色系统分析、建模、 预测、决策和控制的理论.灰色预测是对灰色系统 所做的预测.目前常用的一些预测方法（如回归分 析等），需要较大的样本.若样本较小，常造成较 大误差，使预测目标失效.灰色预测模型所需建模 信息少，运算方便，建模精度高，在各种预测领 域都有着广泛的应用，是处理小样本预测问题的 有效工具(Grey system theory is the research and solution of grey system analysis, modeling, The theory of prediction, decision - making and control At present, some commonly used prediction methods (such as regression score) If the sample size is small, it often results in a comparison Large error, so that the prediction of the target failure Less information, convenient operation, high modeling accuracy, in a variety of prediction collar Fields are widely used to deal with small sample prediction problems Effective tool)

说明：  比较三次样条插值和拉格朗日插值多项式对runge函数插值的效果并作图解释(Comparison of cubic spline interpolation and Lagrange interpolation polynomial interpolation of the Runge function and mapping to explain the effect of)

principal_neumann (nom_maillage) a routine for implementing the EF P1 Lagrange for the Laplace equation following, with conditions Neumann on the mesh nom_maillage.msh

图像处理 灰度化，图像增强，边缘检测，几何特征检测(Image processing gray, image enhancement, edge detection, geometric feature detection)

将混合有白噪声的两个信号的频率提取出来，适合初学matlab的使用(Will be mixed with white noise, the frequency of two signals is extracted, the use of matlab for beginners)

依次输入三个函数即可，若想修改全排列矩阵的大小，可在MATLAB中打开tianchongJ修改(Input function can be followed by three, if amendments to the whole matrix with the size, can be opened in MATLAB to amend tianchongJ)
