噪声环境下的端点检测在语音信号分析和识别中占有重要地位。文中将分形理论中的分形记盒维数应用到端点检测算法中，采用了基于分形记盒维数与短时能零比相结合的端点检测算法，以分形记盒维数为主要判决条件，并在判决门限的设定上采用了自适应机制。-Noise environment endpoint detection in speech signal analysis and identification play an important role. Wen will be fractal theory

盒维数MATLAB计算程序。根据计盒维数原理编写了求一维曲线分形维数的matlab程序-Box dimension MATLAB program. According to box-counting principle of preparing for a one-dimensional curve fractal dimension matlab program

多重分形谱和盒维数的计算，可在matlab环境中直接运行-Multifractal spectrum calculation and box dimension, you can run directly in the matlab environment
