龙格库塔四阶方法，matlab编程，仅供参考(Runge-Kutta fourth-order method, matlab programming, reference)

功能还算完善，可能最后调试有小的问题，但是功能模块基本实现(just do it)

雷达抗干扰，雷达波形调频率捷变抗多目标干扰(Radar jamming, radar waveform modulation frequency-agile multi-target anti-interference)

找函数的零点位置， 返回的是零点的index。 被找的函数须是连续函数 (Find zero points index of a continous function)

matlab函数速查手册,包含全部函数。打开文档，按ctrl和F检索字符能迅速查到需要的函数，对初学matlab的人很有用。我也用这个。(matlab function, Quick Reference, including all functions. Open the document, press ctrl and F to quickly find the character needed to retrieve the function, useful for beginners who matlab. I also use this.)

本代码是PID在S函数中的实现，但不同之处在于，本代码先把PID变成状态空间表达式，更加易懂，为本人独创。(This code is the PID in the S function, but the difference is that, this code to put the PID into the state space expressions, more understandable, for my original.)

KINEMATIC SYNTHESIZE PROJECT MECHANISM SIMULATION this program used for finding the curves that joints in a six-bar mechanism makes. we find this locusts with numerical solution. we divided the 1st link angle to n part, then find the locus of other joints corresponding to that point.
