matlab的准线性集合，可以求出线性参数及误差，并且可以得到极值(matlab quasi-linear collection of linear parameters and error can be calculated, and you can get the extreme value)

3dSIFT特征提取源码，有使用说明，主程序，非常容易使用(3dSIFT feature extraction source, with instructions, the main program, very easy to use)

PDF+论文算法实现源代码"Improving Dictionary Learning: Multiple Dictionary Updates and Coefficient Reuse"由莱斯利N.史密斯和迈克尔·埃拉德，IEEE信号处理快报（2013年）(PDF+ thesis algorithm source code " Improving Dictionary Learning: Multiple Dictionary Updates and Coefficient Reuse" by the Er Ai Leslie N. Smith and Mike Ladd, IEEE Signal Processing Letters (2013))

This code applies local histogram equalization on an input image with a view to improve its contrast ratio. The image is read, converted to grayscale and resized with the inbuilt function of MATLAB. The window size may be changed, however, the window shift is pixel by pixel. The output is definitely a better contrast image as compared to the input but checkerboard effect is evident.

仿真程序：首先需要用一个随机发生器产生（0.1）内的均匀随机数，然后再将该序列映射到对应的幅度电平｛Am｝。然后将这个范围再分成4个相等的区间，这些子区间分别对应于4个信号比特的符号00，01，10，11。检测器观察到r=Am+n，并且计算r和4种可能传输的信号幅度之间的距离，它的输出Bm就是相应于最小距离的信号电平。Bm与真正的的传输信号幅度比较，差错计数器用来对检测器产生的差错计数。(Simulation program: first need to use a random generator (0.1) the uniform random number, then the sequence is mapped to the corresponding amplitude level {Am}. Then this range has been divided into four equal intervals, these sub-intervals corresponding to four signal bits of the symbol 00,01,10,11. Detector observed r = Am+ n, and calculate r and 4 possible transmission distance between the signal amplitude, its output corresponding to the minimum distance Bm is the signal level. Bm and the real rate of transmission of the signal comparison, error detection counter is used to generate the error count.)
