用MATLAB语言实现自动控制里的PID控制器，模型仿真(MATLAB language used to achieve automatic control in the PID controller, model simulation)

code segmentation an image

it is a toolbox which used for denoising

In factor analysis rotations of the loadings are very often applied, whereas in chemometrics these methods are very seldom used. This is in spite of the fact that it is possible to obtain better conditions for interpretation of PCA models on complex data. I here provide an algorithm by which it is possible to apply rotations from the Orthomax family (quartimax and varimax) to a PCA-model.

对声音信号进行butter低通滤波,对录入的信号进行傅里叶变换，同时对比滤波前后，声音信号的不同(Butter sound signal low-pass filtering, of the Fourier transform of input signals, while before and after filtering, different sound signal)

读入一幅256*256图像，将它分成8*8pixel的若干块，对每块做DCT变换，保留Z型顺序的若干变换系数，进行IDCT重构图像，计算重构图像的信噪比(Reading a 256* 256 image, it will be divided into several blocks of 8*8 pixel, keep each optimal Z transformation of sequence number, IDCT transform coefficient calculation reconstruction image reconstruction images,and the signal-to-noise ratio)
