Matlab圆弧插补，只要给定起点与终点，半径，设点圆心方向以及顺逆时针方向即可实现插补(Matlab circular interpolation, given the starting point and end point, radius, set the direction of the point of the center as well as Shun counterclockwise to achieve interpolation)

说明：  能通过添加不同程度的白噪声使一组数据扩展成多组数据(It can expand a group of data into multiple groups by adding different levels of white noise)

本例用matlab语言实现了4QPSK的编解码及通过awgn信道的仿真。采用蒙特卡罗仿真法，得到误码性能，绘制曲线。可用于算法研究或课程学习。(Matlab language used in this case achieved 4QPSK codec and channel through awgn simulation. Monte Carlo simulation method, the BER performance, drawing curves. Algorithm can be used for research or courses.)

在这里，被控量是小车转角，向上回朔是舵机的转角，再向上就是用来控制舵机的PWM波的占空比，也就是说你的被控量是PWM波的占空比；一旦你的 舵机安装方式确定后，小车前轮的左右极限转角也就定死了，也就是说你的PWM波的占空比的变化范围也就确定了，即被控量的论域确定了，以我的为 例是1225到1725，显然S12的模糊机无法直接输出这么大的数值，在此对于输出量的隶属度函数我选用的是单值的，对应9个等级（0-8），即对应9个 PWM占空比值，即对应9个角度值。模糊语言等级、输出等级以及实际PWM占空比值的对应关系如下。 (www.hellodsp.com) 详细出处参考：http://www.hellodsp.com/bbs/viewthread.php?tid=688 )

利用牛顿插值蒙特卡洛法定位移动节点，画出节点运动轨迹并画出定位未知节点轨迹，最后进行误差分析(Using Newton Interpolation Monte Carlo method to locate the mobile node, the node trajectory draw and draw locate the unknown nodes track, the final error analysis)

说明：  matlab工具箱包含大部分的数学函数，非常适合学习(Matlab toolbox contains most of the mathematical function, very suitable for learning)

用路径跟踪法求解不等式约束的凸二次规划，即沿着此路径(或邻域)可以逼近问题的最优解。(With the path tracking method for solving inequality constrained convex quadratic programming, that along this path (or neighborhood) can approximate the optimal solution of the problem.)

如何使用MATPOWER,方便易懂,值得学习(How to use the MATPOWER, easy to understand, it is worth learning)

cordic算法的matlab仿真，小波包分析提取振动信号中的特征频率，语音信号的采集与处理，数字信号处理课设。( cordic matlab simulation algorithm, Wavelet packet analysis to extract vibration signal characteristic frequency, Acquisition and Processing of the speech signal, digital signal processing class-based.)

说明：  1/3倍频程的实现，先fft然后计算上下限频率。(The realization of 1 / 3 octave, FFT first and then calculate the upper and lower frequency.)
