关联规则算法matlab实现
关联规则挖掘是从事务集合中挖掘出这样的关联规则:它的支持度和置信度大于最低阈值(minsup,minconf),这个阈值是由用户指定的。根据支持度=(X,Y).count/T.count,置信度=(X,Y).count/X.count ,要想找出满足条件的关联规则,首先必须找出这样的集合F=X U Y ,它满足F.count/T.count ≥ minsup,其中F.count是T中包含F的事务的个数,然后再从F中找出这样的蕴含式X—>Y,它满足(X,Y).count/X.count ≥ minconf,并且X=F-Y。我们称像F这样的集合称为频繁项目集,假如F中的元素个数为k,我们称这样的频繁项目集为k-频繁项目集,它是项目集合I的子集。所以关联规则挖掘可以大致分为两步:
1)从事务集合中找出频繁项目集;
2)从频繁项目集合中生成满足最低置信度的关联规则。

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.)
