Matlab代码及图像

This program explain how FFT in Matlab works

Matlab源程序代码，用于拟合超二次曲线，曲面的代码，呵呵，与大家一起分享受(Matlab source code for the quadratic curve-fitting, surface code Oh, and that they have enjoyed.)

提出利用电云进行模型重构的算法，该算法基于点云的几何形状特征，很好的算法。(Proposed the use of electric cloud model reconstruction algorithm based on the geometric shape of the point cloud, a good algorithm.)

虚拟示波器,硬件基于NI系列AD采集卡,软件基于Matlab7.9(virtual oscilloscope hardware config: National Instrument A/D card software config: Matlab 2009以上版本)

运用hurst指数检验水文时间序列是否具有趋势性（单组数列&多组数列矩阵形式）(Use hurst index test whether hydrological time series trend (single-set number of columns & multiple columns in matrix form))

三相三线并联型有源电力滤波器模型，可完美运行仿真结果。(Three-phase three-wire shunt active power filter model can run the simulation results perfectly.)

说明：  SVM 现在主要用于故障诊断。他可以解决非线性，小样本。(svm is a means for fault detect.)

加权最小二乘迭代求解多参数估值。用于求解平差问题及其他领域优化问题。(The weighted least-squares iterative solution of multi-parameter estimates. Adjustment for solving optimization problems and other problem areas.)

无忌卡尔曼粒子滤波，希望对大家有帮助。 代码是用matlab实现的(Kalman particle filter out loudly, and they hope to help everyone. Matlab code is used to achieve the)

一、 本程序采用16QAM调制方式，对一串2进制信源进行调制，用升余弦滚降函数进行基带调制，再调到高频信道；在信道上加入高斯白噪声，运用匹配滤波器解调，画出解调星座图，运用最小欧氏距离译码判决，计算误比特率。(First, this program uses 16QAM modulation mode, for a string of two binary source is modulated with a raised cosine roll-off function for base-band modulation, and then transferred to high-frequency channel in the channel by adding Gaussian white noise, the use of matched filter device demodulator, draw demodulation constellation, using the minimum Euclidean distance decoding decision, calculate bit error rate.)
