仿真滚降系数为0.22的平方根升余弦滤波器.m(Simulation of roll-off factor of 0.22 square root raised cosine filter. M)

Matlab源码 计算矩阵各列与其他各列的互相关系数，并按照概率分布利用直方图的形式展示出来。 该互相关系数的定义参考Michael Elad的《Sparse and Redundant Representations》p25 Definition2.3(Matlab code for mutual-coherence of a given matrix)

a fast and precise algoritm to find local maximum or minimum

Image encryption using bitplanes, first image decomposed into their bitplanes,some key image applied for encryption,it will be decrypted if and only if exact key used.

说明：  一个声纹识别的全代码matlab(需要录音)(A full code matlab for voiceprint recognition (recording required))

说明：  使用EEMD对故障信号进行分解，提取不同imf的能量熵，有数据可直接运行。(EEMD is used to decompose the fault signals, extract the energy entropy of different IMF, and the data can be operated directly.)

利用函数实现图像滤波以及采用两种不同的方法生成一个2-D滤波器并设计一个截止频率为0.5的理想低通滤波器(Image filtering in two diffferent way and simulate a low-passfilter.)

说明：  直扩信号BPSK的仿真，采用异或移位的算法实现PN码达到扩频的目的(BPSK DS signal simulation, using different algorithms, or shift the PN code to achieve the purpose of spreading)

This matlab script can get any number of random image patches from any number of images. Usages: Image processing and analysis. Pattern analysis and machine intelligence.
