spectrum-analysis

Speech compression using Linear Predictive Coding. LPC is the oldest and the most basic of modern speech coders. Its a lossy scheme. Playback quality isn t preserved in the process but it can be used in low bit-rate systems.

ECONOMIC LOAD DISPATCH

根据cpso算法给出的一个matlab代码，全，添加测试函数即可运行(According cpso given an algorithm matlab code, full, add test functions to run)

基于加权最小二乘辨识的自适应极点配置算法(adaptive control based on system identification & pole-placement)

说明：  关于livsvm工具箱的一个扩展工具箱，比原来的要多了几种函数(An extension of the toolbox on the livsvm toolbox, to be more than the original function of several)

compressive sensing theory

一维灰度矩，用matlab进行编程，输入为一维灰度序列，输出为边缘值。不能直接处理图像！但有学习研究价值。(One-dimensional gray moment, using matlab programming for one-dimensional gray-scale input sequence, the output value for the edge. Can not directly deal with the image! But learning research value.)

fit_rayleigh_pdf - Non Linear Least Squares fit of the Rayleigh distribution. given the samples of the histogram of the samples, finds the distribution parameter that fits the histogram samples.fits data to the probability of the form: p(r)=r*exp(-r^2/(2*s))/s with parameter: s format:result = fit_rayleigh_pdf( x,y,W,hAx ) input: y - vector, samples of the histogram to be fitted x - vector, position of the samples of the histogram (i.e. y = f(x,a)) W - matrix or scalar, a square weighting matrix of the size NxN where N = length(y), or 0 to indicate no weighting is needed. hAx - handle of an axis, on which the fitted distribution is plotted output: result - structure with the fields s - fitted parameter VAR - variance of the estimation type- weighted LS or not weighted LS iter- number of iteration for the solution
