信号与系统基础练习，演示了数字信号处理中常用的傅里叶变换，分析时域和频域的信息(Signals and systems based practice, demonstration of digital signal processing used in the Fourier transform of the time domain and frequency domain information analysis)

This histogram is a graph showing the number of pixels in an image at each different intensity value found in that image For an 8 bit grayscale image there are 256 different possible intensities , and so the histogram will graphically displays 256 numbers showing the distribution of pixels amongst these grayscale values

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)

MATLAB模型，双馈风电机组基于最大功率跟踪，低风速超速控制，中风速高风速变桨距控制(DFIG MATLABThe wind turbine and the doubly-fed induction generator (WTDFIG) are shown in the figure called The Wind Turbine and the Doubly-Fed Induction Generator System. The AC/DC/AC converter is divided into two components: the rotor-side converter (Crotor) and the grid-side converter (Cgrid). Crotor and Cgrid are Voltage-Sourced Converters that use forced-commutated power electronic devices (IGBTs) to synthesize an AC voltage from a DC voltage source. A capacitor connected on the DC side acts as the DC voltage source. A coupling inductor L is used to connect Cgrid to the grid. The three-phase rotor winding is connected to Crotor by slip rings and brushes and the three-phase stator winding is directly connected to the grid. The power captured by the wind turbine is converted into electrical power by the induction generator and it is transmitted to the grid by the stator and the rotor windings.)
