buck电路，元器件是IGBT，最简单的实例(buck circuit, components are IGBT, the simplest example of)

wsn下的leach算法，是一种最基本的LEACH算法(wsn under leach method is a basic algorithm for LEACH)

matlab做的关于最短路问题的的实现。包含了2个课件。可直接使用。 (Matlab to do to achieve on the shortest path problem. Consists of two courseware. Can be used directly.)

Calculates SNR and PSD of the bit-stream and of the signal

最小二乘回归法（PLSR：partial least squares regression)：是一种新型的多元统计数据分析方法，它主要研究的是多因变量对多自变量的回归建模，特别当各变量内部高度线性相关时，用偏最小二乘回归法更有效。另外，偏最小二乘回归较好地解决了样本个数少于变量个数等问题。(Least squares regression (PLSR: partial least squares regression): a new type of multivariate statistical data analysis methods, the main research is more dependent variable regression modeling of multi-argument, especially when highly linear within each variable When using partial least squares regression method is more effective. In addition, partial least squares regression better solution to the problem of the number of samples is less than the number of variables.)

人工加入椒盐噪声，进行中值滤波去噪,可以自己加入不同密度的椒盐(Artificial adding salt and pepper noise, median filtering denoising, you can add your own salt and pepper different densities)

采用贝叶斯正则化算法提高 BP 网络的推广能力。 在本例中，我们采用两种训练方法，即 L-M 优化算法（trainlm）和贝叶斯正则化算法（trainbr），用以训练 BP 网络，使其能够拟合某一附加有白噪声的正弦样本数据。(Bayesian regularization algorithm to improve the generalization ability of BP network. In this example, we use two training methods, namely LM optimization algorithm (trainlm) and Bayesian regularization algorithm (trainbr), to train BP network so that it can fit a sine additional white noise sample data.)

说明：  模拟光纤中光的行为,是FORG的一部分，有参考价值(light characteristics in fiber lasers,very useful)

识别不同的调制方式，例如AM，psk等。(Identify the different modulation methods, such as AM, psk and so on.)

说明：  基于傅里叶变换的去除图像纹理方法。通过去除频域高亮区域来消除纹理，保留低频信息。(Based on Fourier Transform method to remove the image texture. Highlighted region by removing the frequency domain to eliminate the texture, retain low frequency information.)
