源信号数目估计MATLAB程序，包括IAIC,AIC,MDL,IMDL，MEVARC等5种算法，可得到5种算法在不同信噪比条件下的估计准确率性能曲线。(The number of source signals to estimate the MATLAB program, including five kinds of IAIC, AIC, MDL, IMDL, MEVARC algorithm available algorithms estimated accuracy in different SNR performance curve.)

Principal component analysis (PCA) is a popular tool for linear dimensionality reduction and feature extraction. Kernel PCA is the nonlinear form of PCA, which is promising in exposing the more complicated correlation between original high-dimensional features. In this paper, we first talk about the basic ideas of PCA and kernel PCA, and then focus on the reconstruction of pre-images for kernel PCA. We also give an introduction on how PCA is used in active shape models (ASMs), and discuss how kernel PCA can be applied to improve traditional ASMs. Then we show some experiment results to compare the performance of kernel PCA and traditional PCA for pattern classification. We also implement the kernel PCA-based ASMs, and use it to construct human face models.

说明：  画渗透率曲线 根据已知网格和数据，画等值线。(Permeability curves have been drawn based on HowNet and the data grid, contour drawing.)

matlab画格点风向杆和风羽的函数，在气象绘图中使用较多而且方便(matlab draw grid wind direction and wind feather rod function more in the weather and easy to use drawing)

说明：  function [ret,x0,str,ts,xts]=s4(t,x,u,flag) s4 is the M-file description of the SIMULINK system named s4. The block-diagram can be displayed by typing: s4. SYS=s4(T,X,U,FLAG) returns depending on FLAG certain system values given time point, T, current state vector, X, and input vector, U. FLAG is used to indicate the type of output to be returned in SYS.
