Incremental Linear Discriminant Analysis

信号与系统，信号与系统课设的信号加入噪声以及滤波(Signals and Systems, Signals and Systems course set signal to noise and filtering)

DM码，QR码生成,能够很好地生成二维码，并且支持大小可调(DM,QR barcode，yyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy)

MATLAB 智能控制 刘金琨 包括神经网络和模糊逻辑(MATLAB SMART CONTROL)

This is a source code for ifft of variable size input string. It does not uses MATLAB built-in ifft function.

自己编写的改进ELMAN网络辨识程序.非常实用(I have written procedures to improve the ELMAN network identification. Very useful)

说明：  球体重力异常曲线正演，加噪音后异常曲线，最小二乘反演(Gravity anomaly curve ball forward, plus the noise of abnormal curve, least-squares inversion)

共振解调的源代码，用于对滚动轴承的振动信号处理，并通过fft变换，进行故障诊断(Resonance demodulation source code for rolling bearing vibration signal processing and through the fft transform, fault diagnosis)

说明：  机床时频域信号特征提取，包括均方根值、峰值、峰值因子、峭度因子、脉冲因子、裕度系数、波形因子、功率谱密度、频率方差、均方频率(Eigenvalue extraction)

对于资料短缺的情况进行线性插值，并对差值之后的数据进行保存(For information shortage, linear interpolation)
