学习线性分类器，可以自动识别两类数据点，数据点可以有交叉域，或者没有，共使用了三种方法。(Learning the self-learning process of linear classifier, and then design a linear two-class classifier and do some research based on the feature of linear classifier.)

说明：  这是一个音频时域信号的盲源分离的Matlab程序，效果不错。(This is an audio signal in time domain blind source separation of the Matlab program, the effect is good.)

cvlib_mex为封装了openCV重要函数的库，matlab可以直接调用文件从而运行openCV函数。压缩包中已包含cvlib_mex.mexw64文件，可以直接使用。PS:mexw64适用于windows下的64位matlab。(cvlib_mex important function to encapsulate the openCV library, archive already contains cvlib_mex.mexw64 files can be used directly. PS: mexw64 applicable under windows 64 matlab.)

现需要在高度为600~700KM范围内，回归周期为30天的太阳同步轨道上布置一颗L波段的合成孔径雷达卫星。 1. 请设计合适的轨道参数，并仿真对应轨道下一个运行周期内星下点轨迹图（纬度和经度两个图）； 2. 计算多普勒中心频率，多普勒调频率与纬度的关系图（设姿态角为0°，天线视角20°~60°，推荐35°）； 3. 按高斯投影方式，将星下点轨迹图投影到地图坐标上。(Now requires a height of 600 ~ 700KM range, return period of 30 days are arranged on a sun-synchronous orbit L-band Synthetic Aperture Radar satellites. 1 Please design the appropriate orbital parameters and simulate the corresponding orbit within the next operating cycle nadir trajectories (latitude and longitude two graphs) 2. Calculate the Doppler center frequency, Doppler frequency and the relationship between latitude Figure (set attitude angle is 0, the antenna angle of 20 to 60, recommended 35) 3 Press Gauss projection, the nadir trajectories projected onto the map coordinates.)
