希尔伯特黄变换的代码测试程序，其中主要执行test主程序(Hilbert-Huang Transform code testing procedures, which mainly perform test main program)

说明：  主成分分析.mht：介绍主成分分析的文章 edgepick.m：本程序的目的是实现边缘检测 drawprim.m：找到最大主分量所在的位置，从而在原图象中绘出 practical.m：一个主分量的程序，边缘检测和主分量提取 prin.m：该程序是用princomp函数来提取矩阵的主成分(Principal component analysis. Mht: the article describes the principal component analysis edgepick.m: The purpose of this program is to achieve edge detection drawprim.m: to find the location of the maximum principal component, which in the original image in the draw practical.m: a principal components process, edge detection and principal component extraction prin.m: princomp function of the program is to extract the principal component matrix)

在给定条件下对低通滤波器和高通滤波器的matlab仿真，通过有和没有噪声情况下的对比，观察波形(Under the given conditions the low-pass filter and high pass filter matlab simulation, with and without noise by comparison of the case, observe the waveform)

噪声信号中正弦信号的频谱分析，包括不同信噪比不同周期不同长度(Sinusoidal signal in the noise signal spectrum analysis, including the different cycles of different lengths in different SNR)

说明：  带通滤波。该程序用matlab实现梯形窗的带通滤波，可以直接调用(Band-pass filter. Trapezoidal matlab implementation of the program window with a band-pass filter, can be called directly)

基于matlab的过程辨识，内含多个文件，包括辨识的相关知识。(process identification Based on the matlab，containing multiple files, including identification of relevant knowledge. )

均值，高斯，中值滤波器自编，并附带边界的处理项，最后是一个test.m得检测功能文件(Mean, Gaussian, median filter self, and to deal with border entry, and finally the detection of a test.m may file)

Quantization error and distribution.

数值方法（MATLAB版）第四版的上机答案 语言是matlab 一般每个题目一个文件夹 主程序一般为main文件(Numerical methods (MATLAB version) fourth edition of the machine language is the answer to every problem a general matlab folder as the main file main general)

matlab 基于“轮廓和颜色”来识别花朵的相似性的程序。可以区别出不同类的花儿。比较有趣。(matlab based on the " contours and colors" to identify the similarity of the flowers of the procedure. Can distinguish different types of flowers. More interesting.)
