Brodatz Album 库中任取10幅图像，每幅图分成四小块，得到40幅小图像，取其中一幅小图像，对大图中其余三幅小图进行检索(image retrieval)

这是之前上传的Extract_test_IMFCC程序里面调用的子函数，作配合使用，请看清楚再下载.(This is one subfunction of Extract_test_IMFCC uploaded before.Since pudn.com cannot upload several functions, they must divided.)

课程设计需要运用MATLAB编程实现2ASK,2FSK,2PSK，2DPSK调制解调过程，并且输出其调制后的波形，画出频谱、功率谱密度图，并比较各种调制的误码率情况，讨论其调制效果。(Curriculum design requires the use of MATLAB programming 2ASK 2FSK, 2PSK 2DPSK modulation demodulation process and output modulated waveform, draw the spectrum, power spectrum density map and compare various modulation BER discuss its modulation effect.)

参考外国文献，通过MATLAB程序编写了以两个简单的jqaVXl映射构造一个双混沌互扰 EBJoQRn系统,提出了基于双混沌互扰系统的无线加密算法，具有防窃听的能力，调试无错误。(References to foreign literature, through MATLAB programming the jqaVXl with two simple mapping to construct a mutual interference EBJoQRn dual chaotic systems is proposed based on the wireless encryption algorithm dual chaotic mutual interference system has the ability of anti-wiretapping, debugging errors. )

实现knn算法，压缩包里有程序以及数据，直接打开matlab便可以运行(Implementation of KNN algorithm)

数据降维工具箱，包括一些典型算法，例如pca，lle，mds，lda等。(Data dimensionality reduction tool kit, including some typical algorithms, such as the pca, lle, mds, lda, etc..)
