这是一个实现信号的FM调制的文档，你可以快速实现信号的FM调制(This is a signal of the FM modulation to achieve a document, you can quickly implement FM modulation signal)

本代码包含了多个MATLAB经典程序，其中有：滤波器，线性变换，图像处理等(This code contains a number of MATLAB classical procedures, including: filters, linear transform, image processing, etc.)

常用的各种matlab源码，方便用户使用(Matlab source code commonly used in various, user-friendly)

this is for non linear sliding mode

线性分组码中校验子的分类，详细的把校验子分为几类，没类对应几个错误图样(Linear block code parity sub-classification, detailed sub-divided into several categories to check, no class corresponding to the number of error pattern)

对声音信号的LMS滤波，噪音为固定信噪比的高斯噪声(LMS filtering of sound signals, noise, Gaussian noise for a fixed signal to noise ratio)

用LMS算法实线性均衡结构现光纤信道的自适应均衡，简单实用(LMS algorithm with real-balance structure is linear fiber channel adaptive equalization, simple and practical)

主成分分析法，其本质是实现高纬到低维的分析，用matlab实现的代码(Principal component analysis, by its very nature is to achieve the high latitudes to low-dimensional analysis, implemented with the matlab code)

说明：  多个模式识别算法的matlab代码，包括k近邻、二叉决策树、感知器、fisher线性判别等.(Matlab code of multiple pattern recognition algorithms, including k-nearest neighbor, binary decision tree, perceptron, Fisher linear discrimination, etc.)

这是一个利用MATLAB的GUI编的长直导线周围电磁场的可视化程序。(This GUI provides a visualization of the electromagnetic field induced by a current flowing in a straight wire. The tool also shows the current induced by a rectangular coil that is placed inside the electromagnetic field. The current is calculated using Ampere s Law and the Biot-Savart Law. This demo was created for educational demonstrations. The user can modify the size and position of the coil, as well as the resistance. The current waveform and magnitude can also be specified.)
