如何用Matlab画图 以西东方向为横轴，以南北方向为纵轴。（选适当的点为原点）将国土最西到最东边界在x轴上的区间划取足够多的分点xi，在每个分点处可测出南北边界点的对应坐标y1 ，y2，(How to use Matlab drawing XiDong direction in the north and south direction for the horizontal axis, for the vertical axis. (choose appropriate point for starting point the west to the east land border on the x axis of interval strokes on the locations take enough in every cent point place xi, can detect the north-south border points corresponding coordinates, y2 y1, )

PCA功能函数，使用时只需要编写主函数。(PCA function functions, only need to write the main function. )

找椭圆的中心，用得到了很多算法，可以借鉴！(Find the ellipse center, many algorithms have been used, you can learn!)

本程序是对一些先进控制算法，例如内模算法，史密斯预估算法，前馈补偿算法和预测算法进行仿真．(This procedure is to simulink some advanced control algorithms, such as the internal model algorithm, Smith forecast algorithm feedforward compensation algorithm and prediction algorithm.)

双孤子模拟程序，对光纤中的孤子进行仿真，实验结果较理想(Two-soliton simulation program, the soliton fiber simulation, more satisfactory results)

在压制式噪声调频干扰环境下，应用时频分析的方法（STFT）对线性调频信号进行时变滤波，对干扰进行了初步的抑制。(Under suppress noise FM interference environment, the application method (STFT) variable frequency analysis filtering chirp signal when a preliminary interference suppression.)

This code improves accuracy of TDOA-FDOA method
