观测星表的制备，通过对第谷星表的筛选，选出合适的星体，是星敏感器的重要组成部分，适合刚刚接触的人很快进入状态(Preparation observation catalog, through the screening of Tycho catalog, choose the right stars, is an important part of the star sensor, for just contact people quickly enter the state)

这是一个好用的频偏估计算法的matlab仿真程序,基于混沌的模拟退火算法，数据包传送源码程序。( This is a useful frequency estimation algorithm matlab simulation program, Chaos-based simulated annealing algorithm, Data packet transfer source program.)

说明：  基于lms算法的干扰自适应抵消LMS算法是基于最陡下降法的统计估计的最小均方值算法，令误差的均方值达到最小时的抽头系数的值即为最优解。LMS算法抽头系数w的变化方向为代价方程的负梯度方向。(Lms algorithm based on adaptive interference cancellation algorithm is the LMS steepest descent method based on statistical estimation of the least mean square algorithm, so that the mean square error to achieve the most hours of the tap coefficient value is the optimal solution. LMS algorithm for tap coefficient w, the cost equation changes in the direction of the negative gradient direction.)

说明：  司守奎、孙玺菁《数学建模算法与应用》随书光盘 所有代码 经典小黄书的代码 数学建模比赛必备(Si shoukui, sun xijing. Mathematical modeling algorithm and application. Cd-rom All of the code Classic little Yellow Book code Mathematical modeling competition required)

捷联惯性导航解算程序，内附实实测数据与说明文档可直接使用。 (Strapdown Inertial Navigation solver, included the actual measured data and documentation can be used directly.)

考虑频率偏移的OFDM仿真程序,直接根据经典参考文献编写(Consider the frequency offset of OFDM simulation program, directly from the classic reference preparation)

Solving Nonlinear Equations

三重BOOST升压电路仿真，电压电流纹波小，效果较好(Three BOOST boost circuit simulation, voltage and current ripple is small, the effect is better.)

说明：  计算测地距离，测地距离是众多距离的一种，在高维流行数据分布空间上，欧式距离不再适用，这时就可用到欧氏距离(Computing geodesic distance, geodesic distance is a large distance, popular in high-dimensional data distribution space, the Euclidean distance is no longer applicable, then you can use the Euclidean distance)
