采用matlab语言编写的，用于聚类相关方面的dbscan算法源程序，希望对大家有帮助(using the matlab language for the relevant aspects of clustering algorithm source dbscan hope that we can raise! ! )

matlab 基于双峰法的迭代二值化程序(matlab bmp2 bw )

查找ldpc校验矩阵中的6环，并将其记录到txt文件中(Find ldpc check matrix of the six rings, and its records to a txt file)

对DOA算法中的MUSIC算法进行了改进，使其对DOA的估计更准确,(Algorithm for DOA MUSIC algorithm has been improved to make it more accurate estimates for DOA,)

树形曲线 迭代绘出类似树枝的曲线 第k次迭代产生节点数为nk，第k+1次迭代产生节点数为nk+1(shuxingquxian)

different methods of background subtraction

本代码是用来检测图像的局部不变特征的，主要参考DAVID G. LOWE的sift的论文。变成工具是matlab。(This code is used to detect the image of local invariant features, the main reference DAVID G. Lowe s sift paper. Become a tool is Matlab.)

OQPSK code to run OQPSK in simulink

说明：  gpr例程,是gpml工具箱的demo，比较适合初学者(an example for gpml, can easily get into the gpr field)

利用形态学方法，给ECG信号去基线漂移。基线漂移对心电影响很大。利用形态学上的腐蚀和膨胀，可以处理，但缺点是呈阶梯状，对原始信号有影响，这个是自己编的，未用matlab上的函数。(Morphological method to the ECG signal to baseline drift. Baseline drift on the ECG. Morphological erosion and dilation can handle, but the drawback is that the ladder-like effect on the original signal, this is their own series of unused matlab function.)
