The EnumWindows function enumerates all top-level windows on the screen by passing the handle to each window, in turn, to an application-defined callback function. EnumWindows continues until the last top-level window is enumerated or the callback function returns FALSE.

说明：  遗传算法用于整数规划。约束一些参数为整数，通过GA函数来实现混合整数规划。(Genetic algorithm for integer programming. Bound by some of the parameters of an integer, through the GA function to achieve the mixed integer programming.)

BPSK 数字调制与解调 运行环境 matlab simulink(BPSK Digital Modulations and demodulations in SIMULINK. )

说明：  用快速傅立叶变换计算地形剖面的功率谱密度。(Calculate the power spetral density of the topographic profile)

these are to set of files. first one is used for baro and inertial integration and the erro of inertial. the second one is used for sim of reentry by use of not only its dynamics but also with EKF observants to control reentry
