说明：  matlab 的一个洗牌算法，调用固定区间的随机数生成，然后根据随机数序列交换位置，达到洗牌效果(Matlab call a random number generate function then exchange the numbers according to the random numbers)

说明：  用蚁群算法解决VRP问题，包含基本蚁群算法（我记得不含时间窗约束）(Using ant colony algorithm to solve VRP problem, including basic ant colony algorithm)

本程序用matlab仿真了广义预测控制的显式解法。(This procedure matlab simulation using generalized predictive control method explicit.)

以高斯函数为载波的PPM调制解调，及于理想误码率曲线相比较的误码率曲线(Gaussian function of PPM modulation and demodulation of the carrier, and the desired BER curves compared to BER curves)

matlab方面讲的比较清楚，大家都来下下，很不错的哦。原理与工程应用(book about matlab)
