evaluate the Newton form of the interpolating polynomial

说明：  基于小波变换的图像压缩：小波变换应用于图像压缩。(based on wavelet transform image compression : wavelet image compression used.)

MATLAB编写的基于决策树的ID3算法实现，模式识别，人脸识别。压缩包中包含两个源文件和测试图片，ID3源文件为主代码，fi为求熵函数。(MATLAB prepared based on the ID3 decision tree algorithm, pattern recognition, face recognition. Compressed package contains two source files and test images, ID3-based source code files, fi for the sake of entropy.)

This program code is for compressing a file or image using Huffman coding without any built-in functions.

混沌吸引子，用于处理信号，得到非线性的处理(The chaos attractor, for processing signals, nonlinear processing)

C语言实现的主程序分析法PCA，实现降维处理(C language implementation of the main analysis PCA, achieve dimensionality reduction)

这个是详细的粒子群算法代码。大家可以借鉴参考。(This is the detailed particle swarm optimization code. We can learn from the reference.)

基于matlab的信号FFT频谱分析与显示，含matlab代码(matlab spectrum analysis)

时间序列分析，采用了最小二乘（LS）与自回归(AR)的组合模型，并用MATLAB将其实现(Time series analysis, using a least-squares (LS) and autoregressive (AR) model combination and its implementation using MATLAB)

it is Threshold-ISD algorithm
