PID

实现用systerm generation 完成fft变换。原理清晰，但是结构相对复杂，请大家认真看原理，来自日本书。(Systerm generation completed using fft transform. Principles of clarity, but the structure is relatively complex, please look carefully the principle of everybody, from the Japanese book.)

基于标记的分水岭图像分割算法，是通过MATLAB编写的，算法运行比较快，更改读入图像的路径就可以运行。(Watershed image segmentation algorithm based on mark)

用simulink作的MTI高通滤波器的仿真程序，其中输入信号为高斯色噪声，可以对输出作时域和频域分析。(MTI using simulink for high-pass filter of the simulation program, in which the input signal for Gaussian colored noise can be output for the time domain and frequency domain analysis.)

本程序实现利用自适应滤波器进行系统辨识,效果良好。(This program implements an adaptive filter system identification, to good effect.)

第k小元素（分治法） 给定一个线性序列集，要求求出其中指定的第K小的数的值和位置.如给定n个元素和一个整数i，1≤i≤n，输出这n个元素中第i小元素的值及其位置；(First k small element (divide and conquer) Given a set of linear sequence, where the specified requirements determined the K value and the small number of locations, such as a given n elements and an integer i, 1 ≤ i ≤ n, output this is the n elements of the i-th element value and the position of the small )

XXY 平台移動計算,利用三點位置算出中心進行偏移動作(XXY mobile computing platform using three shift operation center position calculating)

Example of Matlab code

说明：  基于MATLAB的电液伺服系统最优调节器的设计与仿真(The electro-hydraulic servo system based on MATLAB Optimal Regulator Design and Simulation)

含噪的三角波和正弦三角波去噪问题，简便的程序，直接在matlab中打开即可(meaningful)

说明：  pca降维 在pca提取vd后可以利用降维进行更加简便的操作(pca pca extraction vd dimension reduction in the dimensionality reduction can be used after a more simple operation)
