用拉格朗日n次插值方法 对一系列离散点进行插值(N times with Lagrange interpolation method interpolates a series of discrete points)

实现短时傅里叶变换，真的挺好用的，大家可以十四看看呀(TFRSTFT this is a program ,you can try it in you computer)

非常有用，采用DWT变换实现数字水印的嵌入和提取(Very useful, DWT transform was adopted to realize digital watermark embedding and extraction)

源代码包括插值，函数逼近，数值微分，积分，线性及非线性方程，常微分，偏微分方程等的解法(Source code, including interpolation, function approximation, numerical differentiation, integration, linear and nonlinear equations, ordinary differential, partial differential equations such as the Solution)

PDF制作 主要看画PDF相关功能。其他的无用哦。(PDF produced primarily PDF-related features painting. Oh, the other useless.)

Eigenfaces is used to representing a face by projecting original images onto a face space defined by eigenvectors, and then a new face is compared to known faces by calculating the distance between their projections onto face space. (Eigenfaces is used to representing a face b y original projecting images onto a face space d efined by eigenvectors. and then a new face is compared to known faces by c alculating the distance between their project ions onto face space.)
