GPS/INS组合导航中的kalman 滤波(kalman filter in theGPS/INS Integrated navigation )

通信原理的MATLAB编程，满足对课本基础知识的理解，包括调制解调。(Communication Theory of the MATLAB programming to meet the basic knowledge to understand the textbook, including the modem.)

基于MATLAB实现了极坐标下的傅里叶变换，对一个给定 n×n 的二维信号，其计算复杂度等价于笛卡尔坐标下的2D-FFT，可广泛应用于图像处理和分析。(A fast high accuracy Polar FFT algorithm is given in the software package written in MATLAB. For a given 2D signal of size n×n, the algorihtm s complexity is just like in a Cartesian 2D-FFT, which can be used widely in image processing and analysis.)

数学实验中的最速落径问题 A,B是不在一条铅垂线上的两点，在链接A,B两点的所有光滑曲线中，找出一条曲线，使得初速度为零的质点，在重力的作用下，自A点下滑到B点所需的时间最短 (Mathematical experiment steepest drop Path problems A, B is not a vertical line of two points, the link A, B two points in all the smooth curve, to find a curve, the initial velocity of the particle is zero, gravity role, and since the point A to B points decline in the time required for the shortest)
