说明：  截止频率在0.3Hz的巴特沃斯低通滤波器，采用二阶级联进行编程。(In the 0.3Hz cutoff frequency of Butterworth low-pass filter, used to program the second class together.)

提供各种材料和能量的X射线和伽玛射线光子的吸收衰减。(Provides the attenuation and energy absorption of x-ray and gamma-ray photons in various materials.)

This is the m file to read or uff file using matlab, uff file to generate. It is sometimes convenient to issue read, create, so that if someone put a data value.

此目录中的例程执行周期性的以及边界校正性的一维、二维信号的小波分析( The routines in this directory perform periodic- and boundary-corrected wavelet analysis of 1-d and 2-d signals. The main tools for all-purpose use are FWT_PO and IWT_PO.)

Format Data for libsvm

说明：  支持向量机回归用于电力系统短期负荷预测，内包含.m程序和数据(Support vector machine (SVM) regression is used for short-term load forecasting of power system, including. M program and data)

ofdm system with mac simulation

说明：  快速傅里叶变换FFT通用matlab源程序,众所周知，matlab工具箱里的fft函数是内置的，我们无法看到其源代码，为了学习交流方便，特帖出本人以前用matlab语言写的fft通用matlab源程序，以供初学者学习参考之用！(FFT fast Fourier transform common Matlab source, as we all know, the Matlab toolbox fft function is built-in, we can not see the source code, in order to facilitate the exchange of learning and special TIE out I used to write using the Matlab language fft common source Matlab, for beginners to learn reference only !)

介绍趋势外推的数学原理，为实现预测功能的matlab程序提供理论基础(Introduce trend extrapolation of mathematical principles to provide a theoretical basis function matlab program to achieve the forecast)
