LBP (local binary Pattern ) useful for texture classification

对图像进行边缘检测，很简单的一个程序，对初学者很有用！(it detects the edge of the image,a very simple example and it is very useful for the beginner.)

Introduvtion to signal processing with matlab

四元数matlab程序中的FFT计算程序，很好很强大的(Quaternion FFT matlab program calculation program, very good very strong)

说明：  自适应控制的例程 文件samp.m使用matlab6.5通过(adaptive control routines samp.m documents through the use of matlab6.5)

三点二次差值搜索法，基于折线法的信赖域算法。(Three-point quadratic difference search method, trust region algorithm based on the fold line.)

MATLAB est un interpréteur: les instructions sont interprétées et exécutées ligne par ligne. MATLAB fonctionne dans plusieurs environnements tels que X-Windows, Windows, Macintosh

说明：  二进制转换为double型 在matlab2008a上运行无误 可以直接被其他程序调用(Binary is converted to double type in the correct matlab2008a run other programs can be directly invoked)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )
