T2F
T2F子函数，在做傅里叶变换时调用。我一开始编程序时忘了加它，结果WARN ME 说未定义T2F。(T2F subroutine, called when doing Fourier transform. I started to compile the program forgot to add it, and the result is undefined WARN ME said T2F.)

stability_modeling_of_motor
In any power system, stability is always a important parameter. To check the stability of a synchronous generator which is connected with the grid is the power angle and freq need to know.
With the help of this simulation model one can easily find Power angle and Freq.

排队论模型
资源描述。可以说排队现象几乎是不可避免的。
排队论（Queuing Theory）也称随机服务系统理论，就是为解决上述问题而发展
的一门学科。它研究的内容有下列三部分：
（i）性态问题，即研究各种排队系统的概率规律性，主要是研究队长分布、等待
时间分布和忙期分布等，包括了瞬态和稳态两种情形。
（ii）最优化问题，又分静态最优和动态最优，前者指最优设计。后者指现有排队
系统的最优运营。
（iii）排队系统的统计推断，即判断一个给定的排队系统符合于哪种模型，以便
根据排队理论进行分析研究。
这里将介绍排队论的一些基本知识，分析几个常见的排队模型。

Tranfomasi-Fourier-dan-Wavelet
Tranformasi wavelet merupakan perbaikan dari transformasi Fourier.
Transformasi Fourier hanya dapat menangkap informasi apakahsuatu sinyal
memiliki frekuensi tertentu ataukah tidak, tapi tidak dapat menangkap dimana
frekuensi itu terjadi. Jika Transformasi Fourier hanya memberikan informasi
tentang frekuensisuatu sinyal, maka transformasi wavelet memberikan informasi
tentang kombinasi skala dan frekuensi

matlab_FEM_dismesh
DistMesh giving a singular FEM matrix?(Hi
Anyone here with some experience of using DistMesh in finite element code? I m solving the scalar Helmoltz equation in an annular region in 2D:
rho_1 < rho < rho_2
where rho_1 is the radius of a Perfect Electric Conducting cylinder and rho_2 is where the mesh is truncated using an Absorbing Boundary condition.
Now, I ve written code to mesh the region myself (by dividing the region into annular rings and picking a fixed number of points on each ring) and I ve written another program which uses DistMesh to mesh the region. I get a nice solution using my own meshing code but the FEM matrix becomes singular when I use DistMesh. This is the DistMesh Code I used:
Circle with hole
rABC=1.5
rCyl=0.5
fdstring=sprintf( ddiff(dcircle(p,0,0, f),dcircle(p,0,0, f)) ,rABC,rCyl)
fd=inline(fdstring, p )
box=[-2,-2 2,2]
[p,N]=distmesh2d(fd,@huniform,0.04,box,[])
I tried changing box and the 0.04 value (initial edge length). But every time, the matrix becomes sin)

说明： 在处理数据的时候我们经常要算各个区间的频数,但是在matlab中没有这样的命令.当数据比较大的时候自己数就比较麻烦,这里编了个小程序,(Handle data in a time when we often have to count the frequency of each interval, but there is no such matlab in command. When the data when the relatively large number of on its own is too much trouble here编了个small procedures,)
