FT2D

MATLAB code,做点扩散函数和核密度估计的

已知赤经赤纬计算轨道六根数，采用高斯算法(calculate orbit elements（gauss))

This is a trusss problem

这是数字信号处理的一本专业书，里面有许多的经典的例子，可以作为大家学习数字信号处理的教材。(This is a digital signal processing of a professional book, there are many classic examples, as we learn from digital signal processing of materials.)

3D刚性转换，使用matlab编程实现，主要实现坐标轴及相关的空间坐标转换 (3D rigid tranforamtion)

三次样条插值函数，可以直接调用，本人亲测过来，用了matlab现成的函数在里面(Matlab cubic spline interpolation function can be called directly)

说明：  我使用matlab寫的漸層處理程式，希望初學者可以進快上手。(I use matlab gradient processing program to write and hope into the beginners get started quickly.)

PSO_A Alogrithm ,Hybrid particle swarm-based-simulated annealing optimization algorithm

matlab 的各种图像处理与视频处理算法 (very good c++ algorism very good matlab algorism )

本文主要讲述了LTE的几种比较常见的算法，比较容易理解(This paper describes several of the more common LTE algorithms, easier to understand)
