白噪声中单个正弦信号的频率检测与估计 产生，其中是一高斯白噪声，其均值为0，方差为1。用MUSIC方法估计观测数据中正弦波的频率，并给出白噪声方差()un2uσ 与复正弦波的振幅A的估计值。(A single frequency detection and estimation of the sinusoidal signal in white noise, which is a Gaussian white noise with mean 0 and variance 1. MUSIC method to estimate the frequency of sine wave in the observation data, and gives the white noise variance () estimated value of the the un2uσ complex sine wave amplitude A.)

用matlab实现的pca算法，用于将维，适用于各种种试验，如人脸识别程序源码 (Achieved using matlab pca algorithm for peacekeeping, applicable to various types of tests, such as face recognition program source code)

此函数包含了IBP算法的matlab源码程序，共享给大家共同学习(This function includes the IBP algorithm matlab source program, to share common learning)

说明：  近邻传播是一种较新颖的聚类方法，运算量少，聚类速度快。(Affinity Propagation is a new clustering method, which has a low calculation and high clustering speed.)

here to import the pictures and how to segment the picture. how to add the noise. some screen shots will be added this file.

The two-channel QMF bank is one of the earliest and most commonly used filter bank structures.

这个压缩包里包含有有关c和matlab混合编程的一些例子，是我从有关书的光盘中拷贝过来的。欢迎大家下载。(the compressed bundle contains the c and Matlab programming mixed some examples I take it from the book CD-ROM copy overnight. Welcome to download.)
