PSO与SVM如何结合及其实际应用 是一篇把这两个算法结合使用的很好文章(PSO and SVM and its practical application of how to combine these two algorithms is a combination of a good article)

递推最小二乘的老师给的很好的matlab程序(Recursive least squares parameter identification procedures)

利用matlab对声音信号进行傅里叶变换，得到信号的频率图，进而对信号的特征进行分析。(Use of matlab Fourier transform of the sound signals, to get the signal frequency plot, and then analyze the characteristics of the signal.)

实现图像的同态滤波，但是在使用之前需要将图片替换成自己的图片，并且要将图片转换成灰度图片(Achieve homomorphic filtering of the image, but need to be replaced before using the pictures into your own picture, and you want to convert the picture into a grayscale picture)

为什么总是存在了呢?这是用c编的在matlab上实现的信号提取识别源码(Why is always there for them this is the series c achieved in the Matlab Signal Extraction identify source)

时间序列数据分析中的梅林变换工具，可以广泛的应用于数据预测及数据分析,利用最小二乘法进行拟合多元非线性方程。( Time series data analysis Mellin transform tool, Can be widely used in data analysis and forecast data, Multivariate least squares fitting method of nonlinear equations.)

本程序具体描述了利用最小二乘算法对混合信号进行AR参数和其功率谱估计。(This procedure describes the use of least square algorithm for mixed signal AR parameter and its power spectrum estimation. )
