past-music算法，用来进行谐波分量的求解。速度快，效果佳(past-music algorithm used for solving the harmonic components. Fast, good effect)

window 下的lua源码，值得学习,欢迎大家一起学习，下载(lua source window down, it is worth learning, welcome everyone to learn together, to download)

计算一维和二维卷积,基本可以替代Matlab中的conv和conv2函数,程序很方便就可以移植成C语言..(Calculation of one-dimensional and two-dimensional convolution, the basic alternative to Matlab' s conv and conv2 function, the procedure can be easily transplanted into a C language ..)

小波变换相关方法的MATLAB实现，可以在同地幅图像中显示四幅不同的波段，包括三个高频和一个低频。(MATLAB Wavelet Transform Correlation method implemented in the same way images can be displayed in four different bands, including three high and one low-frequency.)

说明：  PCA人脸是识别在matlab的实现程序，包含数据库。(PCA face is to identify procedures in matlab implementation, including the database.)

Using the steepest descent to solve do the optimization work. You can either cll the function or use the difference method to derive the gradient

傅立叶变换能将满足一定条件的某个函数表示成三角函数（正弦和/或余弦函数）或者它们的积分的线性组合。(Fourier transform can meet certain conditions expressed as a function trigonometric (sine and/or cosine functions) or their integral linear combinations.)

本文说明了bezier曲线的渐进迭代性质，是对bezier曲线进行十次渐进逼近迭代，有图形效果来看一斤很接近所给的点(This article describes the iterative nature of the progressive bezier curve, is the bezier curve gradually approaching ten iterations, with graphics that look very close to a pound to the point)

this package contains functions of image gabor fatures extractrion.

NUMERICAL DIFFERENCE APPROXIMATION based on Taylor s expansion---the program give the finite difference coefficient for any number of discrete point. also with that u can differentiate of any function in any order with high accuracy. also u can use it to develop a general finite difference program.
