代码说明:

在模式识别和机器学习中,特征向量是表示某个对象的数值特征的n维向量。机器学习中的许多算法需要对象的数字表示,因为这样的表示便于处理和统计分析。当表示图像时,特征值可能对应于图像的像素,而当表示文本时,特征可能是文本的出现频率

    FDTD方法是把 Maxwell 方程式在时间和空间领域上进行差分化。利用蛙跳式(Leap frog algorithm)--空间领域内的电场和磁场进行交替计算,通过时间领域上更新来模仿电磁场的变化,达到数值计算的目的(FDTD method Maxwell s equations in the field of time and space differencing. Leapfrog (of Leap frog algorithm)- the electric and magnetic fields within the field of space alternating the update time field to mimic the changes in the electromagnetic field to reach the numerical calculation purposes)

    用局部参数最优化方法设计一个模型参考自适应系统,可调增益的初值Kc(0)=0.2,给定值r(t)为单位阶跃信号,即r(t)=A×1(t)。 要求: 1把连续系统离散化(采样时间可取0.1)。 2编制并运行这个系统的计算机程序(注意调整B值,使系统获得较好的自适应特性)。 3记录ym、yp的曲线 记录kp×kc的曲线 记录广义输出误差e的变化曲线。 4在参数收敛后,让Kp=2变为Kp=1,重新观察Kp×Kc及e的变化曲线。 5找出在确定的B值下,使系统不稳定的A值(阶跃信号的幅值),并与用劳斯稳定判据计算的结果比较。 (With local parameter optimization method to design a model reference adaptive system, adjustable gain initial Kc (0) = 0.2, for a given value of r (t) for the unit step signal that r (t) = A × 1 ( t). Requirements: a continuous system discretization (sampling time of 0.1 preferred). 2 compiled and run the system computer program (Note B to adjust the value of the system to obtain better adaptive characteristics). 3 records ym, yp curve record kp × kc curve records generalized output error e curves. 4 parameter convergence, let Kp = 2 into the Kp = 1, re-observed Kp × Kc and e curves. B-5 to find value in determining the next, making the system unstable A value (step signal of amplitude), and using Routh stability criterion and the comparison of the results calculated.)
