matlab中VCA算法的事例 用于高光谱像元解混(the algorithm of VCA)

四旋翼无人机sliding mode backstepping代码(Four-rotor UAV sliding mode backstepping code)

粒子群算法，用于聚类.粒子群在迭代进行的过程中有可能出现早熟收敛 的问题而陷入局部最优解,因此文中在 PSO 算法部 分,设置两个变量对每个粒子和粒子群的状态进行实 时地监控,以便当检测到粒子或粒子群出现早熟收敛 现象时,能及时地对其进行变异操作,增加粒子的多样 性,使其跳出局部极值的束缚,在多维解空间中开始新 的搜索(C_PSO used for clustering)
