Weather-Forecast---MATLAB_Code

合成孔径雷达点目标仿真 大家可以参考一下(synthetic aperture radar target simulation point we can take a look)

用matlab实现二次曲面图绘制，用来绘制曲线图(Draw a graph quadric)

輸入點位於WGS84之大地經、緯度，可於命令窗顯示此點之卯酉圈曲率半徑N、子午圈曲率半徑M及平均曲率半徑R及此點之空間直角坐標X、Y及Z。(Input point is located in the WGS84 geodetic latitude and longitude can be displayed in the command window of the prime vertical radius of curvature point N, M meridian radius of curvature and the average radius of curvature R and the point of the space rectangular coordinates X, Y and Z.)

相机标定matlab源程序，包含测试图，可以为标定提供新的方法，很方便(Matlab source camera calibration, including test plans, we can provide a new calibration method, it is convenient)

TH-PPM（跳时脉冲位置调制）调制的超宽带脉冲形成的源代码(TH-PPM (TH pulse position modulation) modulation of the formation of ultra-wideband pulse source code)

程序实现了生成决策树并使用决策树对离散特征向量进行分类。在判断是否要继续生成叶节点时采用entropy来作为impurity的measurement.(Program and use the decision tree decision tree to generate discrete feature vectors for classification. In determining whether to continue generating leaf nodes using entropy as the impurity of the measurement.)

实现了huffman编码 运行良好 可以在不同的版本中运行(Achieve a huffman encoding)

This function calculates the SAXS integrated intensity on a frame interval ‘start’ to ‘finish’.

说明：  设计一个有干扰的直接序列扩频通信系统， PN码由m序列产生器产生，经过高斯白噪声信道。在接收端接收到的信号包括“有用信号+高斯白噪声+干扰”，将接收信号进行解扩，判决，得到用户的信号检测结果，绘制不同的扩频增益（增益值为10，30，50）下，误比特率随信噪比Eb/N0的变化曲线。(Design of a direct sequence spread spectrum interference system, PN code generated by the m sequence generator, after white Gaussian noise channel. Receives the signal at the receiver, including &quot useful signal+ Gaussian white noise+ interference&quot , will receive the signal despreading, judgments, get the user' s signal test results, draw a different spreading gain (gain value of 10,30, 50), the BER curves with the signal to noise ratio Eb/N0.)

对OFDM系统功率分配贪婪算法的进行了仿真。(Power allocation for OFDM systems greedy algorithm for the simulation.)
