说明：  香农第一定理指出了平均码长与信源之间的关系，同时也指出了可以通过编码使平均码长达到极限值，这是一个很重要的极限定理。(Shannon first theorem that the average yards long with the letter of the relationship between the source, it has also pointed out the code can make the average yards long reach limits, this is a very important Limit Theorem.)

灰色系统的源代码，可以进行短期预测，对比现实数据，得出某因素的影响(The gray system source code, can undertake short-term prediction, )

交通分布中的无约束重力模型，matlab程序(A matlab program of unconstrained gravity model in traffic distribution.)

大学数学实验-清华出版社-姜启源-第4章例题源代码 (Mathematics Experiment-Tsinghua University- Chapter 4 Example)

Can find the phase of the voltage of a power system

光子晶体中吸收介质，其等效介电函数的虚部与实部的共振曲线模拟。(Dielectric absorption in photonic crystals, the resonance curve of the imaginary part of the dielectric function and the real part of the simulation. )

S 变换是 Stockwell（1996）等提出的一个时-频分析方法，它结合了短时 Fourier 变换和小波变换的特点，能够完全无损地实现逆变换。(S-transform is a time-frequency analysis method proposed by Stockwell (1996). It combines the characteristics of short-time Fourier transform and wavelet transform, and can realize inverse transform completely without loss.)

说明：  这是一个pcnn实现的程序，据说是不错的，希望对大家有用，呵呵(This is a pcnn implementation process, is said to be good, we want to be useful, huh, huh)
