我的智囊团项目完整的源代码,可以作为HSS学习的例子,但是注意要导入相应的包! (I think-tank project the complete source code can be used as HSS learning example, but note that you want to import the appropriate package!)

说明：  Mie散射系数也叫米散射的Matlab计算程序。 当球形粒子的尺度与波长可比拟时，发生的散射为米散射。此时必须考虑散射粒子体内电荷的三维分布。此散射情况下，散射粒子应考虑为由许多聚集在一起的复杂分子构成，它们在入射电磁场的作用下,形成振荡的多极子,多极子辐射的电磁波相叠加，就构成散射波。又因为粒子尺度可与波长相比拟，所以入射波的相位在粒子上是不均匀的，造成了各子波在空间和时间上的相位差。在子波组合产生散射波的地方，将出现相位差造成的干涉。这些干涉取决于入射光的波长、粒子的大小、折射率及散射角。当粒子增大时，造成散射强度变化的干涉也增大。因此，散射光强与这些参数的关系,不象瑞利散射那样简单,而用复杂的级数表达，该级数的收□相当缓慢。这个关系首先由德国科学家G.米得出，故称这类散射为米散射。 (Mie Efficiencies)

BP神经网络预测公路运量 1.问题的描述 公路运量主要包括公路的客运量和公路货运量两个方面。据研究，某地区的公路运量主要与该地区的人数、机动车数量和公路面积有关，表1给出了20年得公路运量相关数据，表中人数和公路客运量的单位为万人，机动车数量单位为万两，公路面积的单位为万平方千米，公路货运量单位为万吨。 根据有关部门数据，该地区2010年和2011年的人数分别为73.39和75.55万人，机动车数量分别为3.9635和4.0975万辆，公路面积将分别为0.9880和1.0268万平方米。请利用BP神经网络预测该地区2010年2011年得公路客运量和公路货运量。 (BP neural network to predict the road traffic (1) description of the problem of road traffic including road passenger and road freight volume two. According to research, an area of ​ ​ road traffic and the number of the region, the number of motor vehicles and road area, Table 1 shows the 20 years have to road traffic-related data, the table number and road passenger traffic units for people , million two units of the number of motor vehicles, road area in square kilometers, the highway freight volume was 10 000 tons. According to relevant data, the number of people of the region in 2010 and 2011 were 73.39 and 75.55 million, the number of motor vehicles were 3.9635 and 4.0975 million units, the road area were 0.9880 and 1.0268 million square meters. Please use the BP neural network in the region in 2011, 2010 have highway passenger volume and road cargo.)
