matlab和C++混合编程，利用高斯算法计算Ax=B求解(Solve Ax=B Using combination matlab and c++)

说明：  利用MATLAB进行的画图软件，很齐全，有助于初学者学习画图(Drawing conducted using MATLAB software, it is complete, will help beginners to learn drawing)

说明：  ofdm的bpsk实现，可以在修改后运用与mimo或者vmimo等(realize the BPSK OFDM, can be modified to use with vmimo such as MIMO or)

Extended Finite Element Code

A matlab script to generate scatter plot for the M-ary Modultaion. it asks user to input the value of: M-ary, SNR(in db), number of binary carriers

说明：  针对多边形，求其面积，长宽比，并标记重心(For the polygon, find its area, aspect ratio, and mark the center of gravity)

说明：  matlab应用实例：基于神经网络的分类，用的是iris数据集做例子(matlab applications: classification based on neural network, using the iris data set an example)

在simulink里如何精确建模－好文推荐 Building Accurate, Realistic Simulink Models By Seth Popinchalk An accurate system model is one that performs as expected and produces the desired results. To achieve this level of accuracy you must have a clear modeling goal. For example, will the model be used strictly for simulation, or for generating embedded C code?? This article describes five modeling techniques that can help ensure accuracy: Select the right modeling approach Know your system, understand its dynamics Monitor fo (How accurate modeling in simulink- good text recommended)

《无线通信与原理应用》中QPSK编码的误码率曲线绘制的代码，简洁易懂。有注释，方便修改。("Wireless communications and Principle" in the QPSK coded BER curve drawing code, concise and easy to understand. Notes, easy to modify.)

32个脉冲调制的线性调频连续波发射信号，单目标回波信号中加入了距离时延与多普勒频移信息。数字下变频后再进行脉压与MTD处理从而检测出距离与速度信息。(Chirp 32 pulse-modulated continuous wave transmit signals, a single target echo signal from the delay and added to the Doppler shift information. MTD frequency pulse pressure and then be processed to detect the distance and speed of digital information down.)
