cat map function to scramble a one dimentson sequence

一个慢跑者在平面上沿着他喜欢的路径跑步，突然一只狗攻击他，这只狗以不变的速度跑向跑步者，狗的方向始终指向跑步者，计算并画出狗的运动轨迹（如需其他条件，请自己假定）.(A jogger in the plane along the path he likes running, a dog suddenly attacked him, the dog ran at constant speed running, the dog always point to the direction of running, and calculate and draw the dog)

考虑章动、极移、岁差下历元时刻月球在瞬时平天球坐标系，J2000协议地固系，WGS-84坐标系下的位置速度矢量及转换的matlab源程序(Consider nutation, polar motion, precession next epoch in the instantaneous level of the moon celestial coordinate system, J2000 protocol to the solid line, the position and the velocity vector conversion WGS-84 coordinate system matlab source)

有限差分TVD格式，最简单的，易于理解，适合初学者参照(Finite Difference TVD format, the most simple, easy to understand for beginners reference)

说明：  遗传算法具有强大的全局优化能力，并行计算的快速收敛性(Genetic algorithm has strong global optimization ability and fast convergence of parallel computing)

一维等离子体的ade—fdtd算法程序,也可推广到一般色散介质。(One-dimensional plasma ade-fdtd algorithm program can also be extended to general dispersive media.)

通信系统链路可靠性和节点可靠性的计算并将两者综合(Communication link reliability and node computing system reliability and a combination of both)

说明：  这个模型可以在MATLAB中计算资金的贬值情况，根据利率与时间的长度，最后得到资金的现值或终值( For example, the cost of an asset is $13,000 with a life of 10 years. The salvage value of the asset is $1000. To find the remaining depreciable value after 6 years, use the following commands. Find the accumulated depreciation with the straight-line depreciation function, DEPSTLN. )
