说明：  NPC, active power filter

matlab最新的时频工具箱，更新时间2008.2.15，请将其加压后放于toolbox中，并在matlab中将其添加到搜索路径中使用。(the latest time-frequency matlab toolbox, updated 2008.2.15, please put in after the pressure in the toolbox, and will add it to the matlab search path to use.)

说明：  这段代码的功能是生成高斯滤波器的，用matlab来实现的。(The code s function is to generate Gaussian filter with matlab achieved.)

介绍了3个matlab常用的子程序.有很好的例子加以说明,希望对大家有用.(of three commonly used Matlab routines. Have a good example to illustrate the hope that useful for all.)

混沌粒子群算法。将混沌搜索方法，用在粒子群算法中，避免了粒子群的陷入极小值的缺点。(Chaotic particle swarm algorithm. The chaos search method, use on the particle swarm algorithm, avoid the particle swarm into the minimum faults.)

改进cholesky分解，在cholesky分解基础之上进行改进，不需要分解的矩阵正定条件(Improve the cholesky decomposition, cholesky decomposition in the basis for improvement, positive definite matrix conditions without decomposition)

说明：  多抽样数字信号处理-Matlab Multirate Filtering for Digital Signal Processing: MATLAB Applications Ljiljana Milić University of Belgrade, Serbia(Multirate Filtering for Digital Signal Processing MATLAB Applications.pdf)

a very useful Matlab course with examples and implementations.

混沌理论教材，从不同的角度处理数据，利用最小二乘法消除线性趋势，结果好于差分方法。(Chaos theory textbooks, processing data a different angle, eliminating the use of least squares linear trend, the result is better than the differential method.)

多项式和非多项式曲线拟合，MATLAB的经典案例 (Polynomial and non polynomial curve fitting)
