说明：  里面有三个二维模糊调节器分别实现PID控制器的参数Kp，ki，Kd，的调节。其控制原理：根据前面的偏差e和偏差变化ec将三个模糊控制器FC1,FC2,FC3分别进行模糊化，模糊逻辑推理，解模糊化。最后得到pid控制器参数调节量。(There are three two-dimensional fuzzy controller to achieve PID controller parameters were Kp, ki, Kd, of the regulation. The control principle: According to the previous error e and error change ec the three fuzzy controller FC1, FC2, FC3 were fuzzy, fuzzy logic, defuzzification. Finally, adjust the controller parameters by pid.)

传统的pid控制算法,系统函数是无时滞的,采用增量式的pid控制算法.(traditional pid control algorithm, the system function is without delay, using the incremental pid control algorithm.)

用matlab实现对矩阵的双三次插值算法实现(Bicubic interpolation matlab realize)

数据降维工具箱，包括一些典型算法，例如pca，lle，mds，lda等。(Data dimensionality reduction tool kit, including some typical algorithms, such as the pca, lle, mds, lda, etc..)

混沌图像加密，不错的界面程序，可以添加图片，非常实用(Chaotic image encryption, good interface program, you can add pictures, very practical)

产生随机信号观测样本，不同信噪比和归一化频率。分别用BT法和周期图法估计功率谱密度。(Generate random signal observation samples, different signal to noise ratio and normalized frequency.Using method of BT and cycle diagram method to estimate the power spectral density.)

get Greate Common Divisor of two number (matematics)

This software release consists of an implementation of the algorithm described in the paper: H. R. Sheikh, A. C. Bovik, and G. de Veciana, "An Information Fidelity Criterion for Image Quality Assessment Using Natural Scene Statistics," IEEE Transactios on Image Processing, in publication, May 2005.

MATLAB求解ODE方程，里面的WORD文档详细介绍了各文件的作用(MATLAB ODE solving equations, the WORD document which details the role of each document is also loaded.)

编写的EMD分解程序，希望能帮助到需要的人(Preparation of EMD decomposition process, hoping to help people in need)
