猴群算法 ，不知道怎么转换成matlab下的，所以如果大家谁知道的话，可以告诉我一下(Monkeys algorithm, do not know how to convert matlab under, so if everyone who knows, you can tell me)

这里我们针对三级固体火箭进行研究，主要考虑每一级发动机工作时推力 和比冲 与发动机试车存在摄动偏差（相差 ）时所产生火箭关机点时刻的状态偏差。火箭的飞行的动力学方程可建立在地面发射坐标系中，火箭的第一级、第二级和第三级按照固定的俯仰角程序飞行，第二、三级飞行时已在大气层外，此时可忽略气动力的影响。(Here we study for three solid rocket, the main consideration at every level when the engine thrust and state arising the moment the rocket off point perturbation deviation (difference) in the presence of specific impulse and engine test bias. Outside of the rocket flight dynamics equations can be established on the ground coordinate system launch, the rocket s first stage, the second and third stages according to a fixed elevation angle of flight procedures, and the second, when the third flight already in the atmosphere, this when can ignore the effects of gas dynamics.)

大学生数学建模的书籍以及训练习题，和答案，应该对参赛的选手有一定的帮助。(Mathematical modeling of books and training exercises, and answers for participating players should have some help.)

说明：  使用libsvm进行三分类，svm多分类可以类似编程(Use libsvm for three categories, svm classification can be more similar to programming)

这个是多相滤波的MATLAB程序，做接收机的同学可以参考的(this is a polyphase programme)

说明：  一个用于CDPD调制解调器参数设置的程序。(a CDPD modem for parameter setting procedure.)

计算小波能量谱分析，用于功率谱分析，以及损伤等都可以(Calculating wavelet energy spectrum analysis)
