线性规划的MATLAB程序，希望对大家有用(Linear programming)

蒙特卡洛模拟蒙特卡罗模拟因摩纳哥著名的赌场而得名。它能够帮助人们从数学上表述物理、化学、工程、经济学以及环境动力学中一些非常复杂的相互作用。 数学家们称这种表述为"模式"，而当一种模式足够精确时， 他能产生与实际操作中对同一条件相同的反应。但蒙特卡罗模拟有一个危险的缺陷: 如果必须输入一个模式中的随机数并不像设想的那样是随机数， 而却构成一些微妙的非随机模式， 那么整个的模拟(及其预测结果)都可能是错的。(Monte Carlo simulation)

由于卫星与用户接收机二者的连线方向上存在相对运动，因此引起了载波和伪码的多普勒效应，再加上接收机晶体震荡频率漂移和卫星时钟频漂等原因。接收机实际接收到的卫星载波中心频率一般不再等于信号被发射时的标称频率，这就需要接收机在载波频率一维对信号进行搜索。同时，由于卫星到接收机的距离时刻变化，加上接收机始终相对于GPS时间的偏差又并不固定，因而接收信号的伪码相位值也在改变，所以接收机也要在码相位一维对信号进行搜索。扩频信号的捕获是一个对目标信号频率域和相位域进行的二维搜索过程。(Because of the relative motion between the two of the satellite and the user receiver, the Doppler effect of the carrier and pseudo-code is caused, and the frequency drift of the oscillation of the receiver crystal and the frequency drift of the satellite clock are added. The frequency of the satellite carrier center that the receiver actually receives is generally no longer equal to the nominal frequency of the signal being transmitted, which requires the receiver to search the signal in one dimension of the carrier frequency. At the same time, because the distance between the satellite to the receiver is changed, the deviation of the receiver always relative to the GPS time is not fixed, so the pseudo code phase value of the received signal is also changing, so the receiver also searches for the signal in the code phase. The acquisition of spread spectrum signal is a two-dimensional search process for the frequency domain and phase domain of the target signal)
