Independent Component Analysis ICA

本代码描述了LDPC码的BP译码算法的每一个步骤，详尽。(This code describes the decoding algorithm for LDPC codes BP each step, detailed.)

Matlab allows the use of MEX files –MEX files are pre-compiled files that are called from Matlab –Can be compiled from Matlab .m files –Can also be compiled from external C++ code. • This will be our focus

Signature normalization for signature recognition

用MATLAB实现fft变换，很easy，源代码如下(MATLAB，fft)

MATLAB GUI实现动态画图曲线的源程序代码(MATLAB GUI for dynamic drawing curve of the source code )

灰色系统的matlab实现程序!可以预测未来态势发展(Gray system procedures matlab realize! Can predict the future trend of development)

该源码在matlab平台上运行,实现的功能是利用hough变换检测图像中具有一定长度的直线,并将直线从整个图像中提取出来.不仅如此,还可以通过计算分析求出对应直线的斜率.(The source platform to run in matlab, the function is to realize the use of hough transform detection image has a certain length of a straight line, and a straight line from the entire image extracted. Not only that, but can also be obtained by calculating the analysis corresponds to the slope of a straight line.)
