基于BP神经网络的轴承故障诊断

说明：  《Hyperspectral Remote Sensing》是一本关于高光谱遥感图像处理与应用的英文经典书籍，对于学习高光谱遥感图像的人员有很大的帮助。(&quot Hyperspectral Remote Sensing&quot is a book on hyperspectral remote sensing image processing and application of the English classics, hyperspectral remote sensing images for learning the staff is very helpful.)

可读取采集卡上WMD格式数据文件，分析行波故障信号的故障点及波头位置。(Can read acquisition card format data files on WMD, analyzes the traveling wave fault signal fault point and wave head position. )

说明：  用角谱法和傅里叶变换，计算衍射传输，及其衍射效率(The angular spectrum method and the Fourier transform to calculate the diffraction transmission, and the diffraction efficiency)

说明：  狼群算法基础原始程序，内含对应的2014年狼群算法原始论文(The basic original program of Wolf pack algorithm, including the corresponding original paper of 2014 Wolf pack algorithm)

刚注册，第一次发，学习学习。 利用matlab仿真2fsk(Just registered, the first hair, learning to learn. 2FSK simulation using matlab)

图像位平面分割，高斯金字塔生成与复原，图像4因子下采样等基本操作，有详细的代码注释。(Image bit-plane partition, Gaussian pyramid generation and recovery, image down-sampling factor 4 basic operations, the code has detailed notes.)

Base class for all test runners.

FDTD仿真二维圆柱隐身衣，附理论推导和matlab程序 二维TM波（Hx Hy Ez），传的是TE波的程序其实道理是一样的。边界采用UPML，平面波靠总场/散射场引入(Two-dimensional TM wave (Hx Hy Ez), TE wave transmission is in fact the procedure is the same reason. Boundary using UPML, a plane wave by the total field/scattered field into )

Simple code for clipping

说明：  利用软硬阈值函数和改进的阈值函数对含噪心电信号进行去噪处理(Soft and hard thresholding function and improved threshold function are applied to denoise electrical signals containing noises.)
