该压缩包实现二维的DCT变换和逆DCT变换，可以对图像做DCT变换和逆DCT变换，实现非常简洁，速度很快。(the compressed 2D DCT and the inverse DCT. Images can be done DCT and inverse DCT achieve a very simple, very fast.)

带约束条件的梯度投影法matlab程序，经过实测，可以使用(With the constraints of the gradient projection method matlab program, after the measurement, you can use)

solar,光伏发电单元，自动生成输出特性曲线(solar, photovoltaic cells, automatically generate output characteristic curve)

Approximate subspace-based iterative adaptive approach for fast two-dimensional spectral estimation

说明：  利用小波分析具有时频局部化特性和熵能对系统状态进行表征的特点，将小波分析和熵结合起来，定义了3种小波熵（小波能谱熵、小波时间熵、小波奇异熵），并给出其算法，揭示了这3种小波熵对系统故障表征的机理，对两种理论信号和基于PSCAD/EMTDC仿真的输电线路故障信号(Based on the characteristics of time-frequency localization of wavelet analysis and entropy energy to represent system state, three kinds of wavelet entropy (wavelet energy spectrum entropy, wavelet time entropy and wavelet singular entropy) are defined by combining wavelet analysis and entropy, and their algorithms are given. The mechanism of these three kinds of wavelet entropy for system fault characterization is revealed. The results show that the three kinds of wavelet entropy can be used to characterize system fault Road fault signal)

第七章的多维非线性辨识的MATLAB程序例7.2用神经网络学习二维非线性函数 ，是侯媛彬和汪梅的系统辨识课本上第七章的的实验。(Chapter VII of the multi-dimensional non-linear identification procedure Example 7.2 using the MATLAB neural network to learn two-dimensional nonlinear function, is Houyuan Bin and Wang Mei system identification textbook Chapter VII of the experiment.)

将图形加以高斯噪声或者椒盐噪声。为图像处理的一种可靠的加噪方法。BLUR Test problem: digital image deblurring(Gaussian noise or the graphics to be salt and pepper noise. As a reliable image processing method with noise. BLUR Test problem: digital image deblurring)

这是对广义高斯分布中两个参数alpha,beta的估计方法，对自然图像的大量统计特征就符合这一分布。(function [f, g] = dggbeta(beta, absx) DGGBETA Derivative of generalized Gaussian pdf with respective to beta [F, G] = DGGBETA(BETA, ABSX) Return partial derivative and second order partial derivative This is an utility function for GGMLE ABSX is the distance of the data from the mean Function is undefined for negative beta if beta <= 0 f = NaN g = NaN )

基于迭代法自动阀值分割matlab源文件，不使用matlab自带的库函数！！！(Iterative method based on image segmentation)

经典的功率谱估计，平均周期图法实现，已经加上了详细的注释(Classical power spectrum estimation, the average periodogram implementation, has added a detailed comment)
