信号处理中波束形成时各种加权矩阵，包括长球函数权值和Kaiser加权(Beamforming signal processing for the various weighting matrix, including the prolate spheroidal functions and Kaiser weighting function)

利用wolf法编写的lyapunov指数程序(Using the method of Wolf lyapunov index program written )

说明：  用四阶古典RK方法解初值问题： 取h=1/8。每隔8步打印出数值解与真解的值（u(t)=(t^2)/2-t），画出它们的大致图像，并对产生的结果做出解释。 (with four bands classical RK method for initial value problems : from h = 1/8. Every eight-step numerical solution print and in the true value (u (t) = (t ^ 2)/2-t), they generally draw the images, as well as the results of an explanation.)

此程序为测试窗函数宽度对时－频分辨率的影响，即测不准原理，对时间分辨率和频率分辨率只能取一个折中，一个提高了，另一个就必然要降低，反之亦然。(This procedure for the test window function width on- frequency resolution, that is, the uncertainty principle, the time resolution and frequency resolution can only take a compromise, an elevated, and the other is bound to reduce, and vice versa .)

IMC-PID是利用内模控制原理来对PID参数进行计算，本程序的性能已经达到较高水平，部分实现了追踪测速迭代松弛算法。( The IMC- PID is using the internal model control principle for PID parameters is calculated, The performance of the program has reached a high level, Partially achieved tracking speed iterative relaxation algorithm.)
