在matlab绘图中可设置函数曲线图视角的用户界面的m函数。(Drawing in matlab function to set the curve of the user interface perspective m function.)

本文是关于QPSK测试的matlab源码(This article is about the QPSK test matlab source)

以“一主三从”主从多机通信系统为物理模型，研究应用马尔可夫链建立仿真算法及蒙特卡洛法建立了数学模型，通过将完整的系统元件化，并对每个元件创立各自的状态转移机模型，仿真运行状态，实现了对于这一通信系统的可靠性建模评估。(" One the main three from the" master-slave multi-communication system for the physical model to study the application of Markov chain Monte Carlo simulation algorithm and the mathematical model established through the will of a complete system components, and the creation of each component their respective state transition model, the simulation run, and the realization of a communication system for the assessment of the reliability of modeling.)

说明：  图像摆正，把任意角度的图像摆正Straighten images, straighten out images of the arbitrary Angle(Straighten images, straighten out images of the arbitrary Angle)

it is the matlab model for simulation of the class d chopper with full details of parametrs

matlab命令大全，包括几乎所有的matlab命令，中文版，比使用help命令查询方便很多，是matlab用户的好帮手。(matlab command Guinness, including almost all of matlab command, the Chinese version, than the use of help command a lot of inquiries convenience is a good helper matlab users.)

说明：  MATLAB提供了多种方式从磁盘读入文件或将数据输入到工作空间，即读取数据，又叫导入数据；将工作空间的变量存储到磁盘文件中称为存写数据，又叫导出数据。(MATLAB provides a variety of ways from the disk is read into a document or data entered into the work space, that is, read data, also known as import data will work variable storage space to keep the disk file is called to write data, also known as export data .)

临床测试的各种心电信号数据dat格式，可以用matlab来进行处理(ecg signal processing using matlab，there a lot of data in it.)
