How to use the ordinary Voronoi partition generator. The m-files also have
their own help documentation that you can view in Matlab. This code creates
a bounding polygon that is a square. Then it randomly creates 10 points
and then creates and draws the partition.
bounds = [0, 10, 10, 0 0, 0, 10, 10]
points = 10 * rand(2, 10)
regions = voronoi(bounds, points)
drawRegions(bounds, regions)
================================
This is a brief set of instructions on how to use the Multiplicatively-
weighted Voronoi partition generator.
Each of the m-files has a help section, so in Matlab you can call:
help mwvoronoi
help drawRegions
Here is an example that creates a bounding polygon, a square with side
length 10. Then it randomly creates six points with random weights.
Finally, the code draws the resulting partition.
bounds = [0, 10, 10, 0 0, 0, 10, 10]
points = 10 * rand(3, 6)
regions = mwvoronoi(bounds, points)
drawRegions(bounds, regions)
Enjoy!

1） 计算 和 各自的自相关函数，并画出其函数图形。根据此选择合适的延时，以实现谱线增强。
2） 产生一个 序列。选择合适的 值。让 通过谱线增强器。画出输出信号 和误差信号e(n)的波形，并分别与 和 比较。
(Computer Experiments:
1. Consider an AR process x(n) defined by the difference equation
where v(n) is an additive white noise of zero mean and variance .The AR parameters and are both real valued:
a) Calculate the noise variance such that the AR process x(n) has unit variance .Hence , generate different realization of the process x (n).
b) Given the input x (n), an LMS filter of length M = 2 is used to estimate the unknown AR parameters and . The step size is assigned the value 0.05. Compute and plot the ensemble average curve of and by averaging the value of parameters and over an ensemble of 100 different realization of the filter. Calculate the time constant according to the experiment results and compare with the corresponded theoretical value.
c) For one realization of the LMS filter, compute the prediction error
And the two tap-weight errors

Side impact accidents against a tree or pole remainthe most dangerous accident scenarios in rally
cars. Statistical data shows that 52 of the fatalities between 2004 and 2009 concern crashes
against a rigid pole by the track sides, whilst among those more than 60 were side impacts. Despite
the present scientific efforts, rallying cars side impacts are still among the least understood primarily
due to limited space between the occupant and door sill, evolving safety regulations and vehicle
dynamics.
