MATLAB_4_DQPSK

Hi.the program i uploaded is useful for the electromagntic subjects. variations in the wave when it travels through the different media

说明：  二维离散小波变换和重构（对高通和低通系数分别卷积。。。）(Discrete wavelet transform and reconstruction (high-pass and low pass convolution coefficients...))

LDPC码的C语言编译码，包含校验矩阵，备注等等(LDPC codes codec C language, including parity check matrix, notes, etc.)

说明：  多分类孪生支持向量机,主体是-1 1的2分类孪生支持向量机，采用onevsone改编成多分类的孪生支持向量机(multi classification twin support vector machine, kernel code is binary-classification twin support vector machine ,constructed it as a multi classification twin support vector machine by using OneVsOne coding)

FCM聚类算法的MATLAB实现，还有一些聚类算法的matlab其他实现方法。(FCM clustering algorithm of MATLAB realize, there are some clustering algorithm matlab realize other methods.)

数据聚类和模式识别MATLAB工具箱，完整的程序集(Data clustering and pattern recognition MATLAB toolbox, complete assembly)

图像的置乱处理，包括了模板置乱法，幻方置乱法和图像的一个基本加密方法——4bit置换(Scrambled images, including the template scrambling method, magic squares and image scrambling method is a basic encryption method- 4bit replacement)
