直接转矩控制方面的例子，希望能给大家提供帮助(Examples of direct torque control, hope that they can help)

说明：  介绍了如何使用matalab对信号系统进行仿真，对初学者很适用(This text contains a comprehensive discussion on continuous and discrete time signals and systems with many MATLAB&reg examples. It is written for junior and senior electrical engineering students, and for self-study by working professionals. The prerequisites are a basic course in differential and integral calculus, and basic electric circuit theory.)

任何一个三角形的2D，3D ND点的面积和角度计算。这个简单的功能使用三点作为输入可以是二维，三维和…。并将计算区域和角度的三角形(Any of a triangle area and angle of the 2D and 3D ND point calculations. Simple functions use three points as input can be two-dimensional, three-dimensional and ... And calculate the area and angle of the triangle)

心电信号压缩，利用小波理论，基于小波变换的心电信号的压缩。(Ecg signal compression, using the theory of wavelet, the compression of ecg signals based on wavelet transform.)

说明：  对信号进行频域特征提取，先通过傅里叶变换得到信号频谱，再计算频谱特征，包括重心频率，均方频率和频率方差(Firstly, the frequency spectrum of the signal is obtained by Fourier transform, and then the spectrum characteristics, including center of gravity frequency, mean square frequency and frequency variance, are calculated.)

对一幅图像加入高斯噪声和椒盐噪声后，分别进行均值滤波和中值滤波，比较两种滤波方法的优缺点(Of an image by adding Gaussian noise and salt and pepper noise, the mean filter, respectively, and median filtering, comparing the advantages and disadvantages of the two filtering methods)

基于Matlab模拟的ask，psk以及fsk调制方式(Matlab-based simulation ask, psk and fsk modulation)

M/M/1 模型,主要用来求解单对单服务台的模型，过程比较简介，适合任何分布(M/M/1 model, mainly used to solve the one-on-one help desk model, the process is relatively brief, suitable for any distribution)

说明：  使用matlab中的多个命令来画出二维、三维的图像(Using matlab multiple commands to draw two-dimensional, three-dimensional images)
