说明：  合成孔径雷达成像中的一种常用的算法，距离多普勒算法(a common algorithm of Synthetic aperture radar imaging : distance Doppler algorithm)

差分进化算法，可以用于多目标优化，可以分享的啊。(Differential evolution algorithm, can be used for multi-objective optimization, can share the ah.)

matlab中信噪比计算程序，可以检验使用matlab内置函数添加的噪声是否正确(Can be tested using matlab citic noise ratio calculation, matlab built-in functions to add noise is correct )

灰色预测方法，重点讲解的灰色预测的基本理论和详细实现方案，给出了5个用matlab编好的灰色预测程序的实现。(Grey prediction method to highlight the basic theory of gray forecast and detailed implementation gives five good gray prediction using matlab program implementation.)

CT程序重建，根据傅立叶变换radon变换进行CT投影重建(CT Graph reconstruction)

牛顿法的MATLAB，随便写的水平有限请谅解(Newton' s law of MATLAB, low level of random write requests with the understanding)

包括：使用控制变量蒙特卡洛法和一般蒙特卡洛法的欧洲期权看涨价格程序；使用蒙特卡洛计算定积分；使用B-S公式计算期权价格。 ( Including: European call options price procedure using control variable Monte Carlo method and general Monte Carlo method using Monte Carlo calculation of definite integral use the B-S formula to calculate the price of option.)

this is the code about display and plot average

用Matlab处理GPS导航卫星观测数据的程序，也就是O文件，Rinex 2.11版本，代码仅200多行，且包含大量注释，于2017.12.2日调试通过，可顺利读取体积达10M+的O文件，读取的数据准确无误。函数调用格式： [APXYZ DeltaHEN signal_type obsdata] = read_obs(‘krgg3340.17o’)(Using Matlab to process GPS navigation satellite observation data program, that is, O file, Rinex 2.11 version, the code is only more than 200 rows, and contains a lot of annotations. It debugged on 2017.12.2 day. It can smoothly read the O file with volume up to 10M+, and the data read is accurate.)
