模式搜索法源程序。模式搜索方法是求解最优化问题的一种直接搜索方法,它不用目标函数与约束函数的导数信息而只用函数值信息,是求解不可导或求导代价较大的最优化问题的一种有效方法。(Source model search. Pattern search method for solving optimization problems is a direct search method, it should not be the objective function and constraint function information of the derivative function only information is the solution of non-derivative or derivative of the cost of a larger optimization problem of a effective way.)

(digital watermark embedding and detection, Copy, the writer Mao Li Purpose : an algorithm to achieve the embeding watermark ing to a image by Extra bloking and hvs. then detect the watermarking by comparability .)

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.)
