The liear principle analysis code

ChunmingLi编写的levelset程序，主要用于图像分割。(ChunmingLi levelset prepared by the procedure used mainly for image segmentation.)

Optical Character Recognition

图像的特征提取，用于图像的分类研究 主要是用的MATLAB(Image feature extraction)

Designs a linear phase FIR lowpass filter such that it: - minimizes maximum stopband attenuation - has a constraint on the maximum passband ripple This is a convex problem (when sampled it can be represented as an LP). minimize max |H(w)| for w in the stopband s.t. 1/delta <= |H(w)| <= delta for w in the passband ( where H is the frequency response function and variable is h (the filter impulse response). delta is allowed passband ripple. )

本书对matlab由简单到难的介绍，尤其是在矩阵那一节，对很多细节处，一些平常书都不回介绍到的命令进行了详细介绍( the book introduce matlab from easy to hard，especially in introducing matrix，it tell many details which other book don‘t introduce)

Digital modulation demodulation

快速傅氏变换的简单实现，可进行快速频谱分析(Simple implementation of the fast Fourier transform, fast spectrum analysis)

The Frequency Domain Decomposition (FDD) is an output-only system identification technique popular in civil engineering, in particular in structural health monitoring. As an output-only algorithm, it is useful when the input data is unknown. FDD is a modal analysis technique which generates a system realization using the frequency response given (multi-)output data

用于建立主成分分析模型，三相光伏逆变并网的仿真，MinkowskiMethod算法 。( Principal component analysis model for establishing, Three-phase photovoltaic inverter and network simulation, MinkowskiMethod algorithm.)
