通过运用数学软件matlab绘制不同颜色形状的花坛曲面(By using mathematical software matlab draw a different colors and shapes of flowerpot surface )

共轭正交镜像滤波器组的设计。令N=22,wp=0.45pi,用切比雪夫最佳一致逼近法设计单带滤波器G(z),在得到半带滤波器Hlf(z). (conjugate mirror filters orthogonal design. Order N = 22, wp = 0.45pi. Chebyshev with the best approximation consistent single-band filter design G (z), with the half-band filter Hlf (z).)

在数值方法中，用Matlab实现Gaussian Hermite， 此方法用来计算数值积分(Gaussian Hermite)

下垂控制仿真，采用PF-QE下垂，能够按给定的有功和无功进行仿真(Droop control simulation, using the PF-QE drop, can be simulated according to the given active power and reactive power)

在倒立摆摆角及摆速很小的时候，实现基于sugeno模型的倒立摆模糊控制(Monotonously in inverted pendulum angle and velocity very young to realize sugeno Model Based Fuzzy Control of Inverted Pendulum)

matlab各种周期信号的频谱分析matlab各种周期信号的频谱分析。(matlab various periodic signal range of the spectrum analyzer matlab cycle spectrum analysis of signals.)

您好： 这个matlab程序是用周期循环检测算法检测：首先运行a.m程序，通过此程序运算得出循环频率a值；再运行zhouqi.m程序，对a值进行确定，通过周期循环算法对信号进行检测； (Hello: This procedure is used matlab cycle detection algorithm: First run a.m program, obtained through the operation of this procedure cyclic frequency of a value to run zhouqi.m procedures, a value determined by the signal cycle algorithm detection )

产生随机比特流 并进行2ASK 2FSK 2PSK 2DPSK调制(Generate random bit stream and make 2ASK 2FSK 2PSK 2DPSK modulation)

说明：  这个程序主要是对英特网无标度网络的仿真，很有用的哦(This program mainly for the Internet scale-free network simulation, very useful oh)

一维功率谱密度计算程序，可以选择是否加窗，加那种窗(1D power spectral density caculation routin base on fft )
