2011年全国大学生数学建模竞赛A题程序(the answer for the first problem in 2011 MCM)

分形维数应用与MATLAB实现——借助分形维数理论，对二维图像和语音信号进行分析计算，让读者真正掌握分析盒维数的计算。(Fractal dimension and MATLAB realization——With the fractal dimension theory, the two-dimensional image and speech signal analysis and calculation, so that the reader grasp the real calculation cartridge dimensions.)

分数阶tid控制能实现普通tid所部能实现的功能，并且更稳定、更有效果。(Fractional control to achieve common tid tid to achieve the functions of his troops, and more stable, more effective.)

ovsf is an orthogonal code for multiuser environment

各种求解非线性方程组的算法程序，包括牛顿法及变形，不动点迭代，共轭梯度等等等等(Various algorithms for solving nonlinear equations procedures, including Newton and deformation, fixed point iteration, conjugate gradient, etc., etc.)

该源码利用三帧差分法实现了运动目标的检测，比传统的帧差法效果要好，阈值可根据自己使用的视频自行调节。本压缩包没有相应的视频，需要自己载入，并重新设定位置。 

变频信号的快速FFT变换，能准确的给出信号的频谱特征(Fast FFT of the signal frequency, can give accurate spectral characteristics of the signal)
