基于MATLAB语言的局部增强的程序，供大家参考，适合入门者(MATLAB language based on local enhanced procedures for your reference, suitable for beginners)

提取信号七个基于瞬时信息的特征：零中心归一化瞬时幅度功率谱密度的最大值,零中心归一化瞬时幅度绝对值的标准偏差，零中心非弱信号段瞬时相位非线性分量绝对值标准偏差，零中心非弱信号段瞬时相位非线性分量标准偏差，零中心归一化的非弱信号段瞬时频率绝对值的标准偏差，一个信号段的归一化瞬时频率功率谱密度的最大值，根据信号 QPSK 和16QAM在 XI 轴投影的不同表现，提出特征参数。(Extraction based on instantaneous information signal of seven characteristics: zero center normalized instantaneous amplitude of the maximum power spectral density, zero-center normalized standard deviation of the instantaneous rate of absolute zero center section of non-weak signal instantaneous phase nonlinear component absolute value of standard deviation, non-zero center section of the weak signal non-linear component of the standard deviation of the instantaneous phase, zero-center non-normalized absolute value of the weak signal section of the standard deviation of the instantaneous frequency of a signal segment of the normalized power spectral density of instantaneous frequency maximum, according to the signal QPSK and 16QAM in the XI-axis projection of the different performance of the proposed characteristic parameters.)

随机减量技术（Random Decrement Technique-RDT），其主要是利用样本平均的方法，去掉响应中的随机成分，而获得初始激励下的自由响应，(Random decrement technique (Random Decrement Technique-RDT), whose main method is to use the sample mean, remove the random component of the response, and the response to the initial excitation freedom of)

说明：  数值分析一题， 曲面拟合 5个表达式(that a numerical analysis, surface fitting 5 expression.)
