运用EMD的过程中，想要画出边际谱，边际谱程序的详细代码。(In the process of using EMD, you want to draw the marginal spectrum, the detailed code of the marginal spectrum program.)

将低动态范围图像通过色调映射技术转换为高动态范围图像，对图像的亮度通道进行加强，该算法是reinhard代码进行实现的。(The low dynamic range image is transformed into high dynamic range image by hue mapping technology, and the brightness channel of the image is enhanced. The algorithm is implemented by Reinhard code.)

牛顿多项式拟合卫星精密星历，默认15分钟类型，内插至30s(Newton)

V_RESAMPLE is a Matlab function implementing nonuniform data sampling. It resamples the input data at the specified, continuously variable sampling rate, which may be locally higher or lower w.r.t. the original rate. Aliasing terms are taken care of by appropriate smoothing.

说明：  由于matlab提供了一些很有用的计算方法 但是大部分用户只用到其中一部分的功能 所以写了一个包括解方程，矩阵计算，排序功能的代码(As matlab provides some very useful method but most users only use part of the function it was a including solving equations, matrices, and sorting code)

Solver for linear ecuations system (SOR-successive over relaxation), very usefull!!.

从IMU中提取数据，计算出速度、位移，从而得到运动轨迹，实现定位功能(Calculate velocity and displacement data of IMU, thus we can get movement track and achieve locate function.)

说明：  MATLAB命令汇总，对基本函数的使用说明，及快捷键(MATLAB command summary, the basic function, the instructions for use and keyboard shortcuts)

用matlab控制PID参数，进行调整，可实现仿真，适合初学者(Matlab PID control parameters to be adjusted, enabling simulation, suitable for beginners)
