说明：  hough变换，可以经过图像的边缘点实现霍夫变换，即实现空间转换！(hough transform, image edge points can be achieved through the Hough transform, that is to achieve space conversion!)

Plot examples with codes in matlab

PF,EPF,UPF的对比仿真代码，可以很直观的看出各种算法之间的差别及各自的优缺点。可直接运行。(PF, EPF, UPF contrast simulation code, it is intuitive to see the differences between the various algorithms and their respective advantages and disadvantages. Can be directly run.)

关于matlab的方面的一些源代码。可以实现多项式函数计算，插值计算，和傅里叶变换，等等(Some aspects on the matlab source code. Polynomial function can calculate, interpolation, and Fourier transform, and so on)

用于对彩色图像进行边缘检测的简单matlab代码(color images edge detection)

给出了reliefF算法的matlab源代码，该算法用于处理目标属性为连续值的回归问题。是由relief算法拓展所得，可以处理多类别问题。(ReliefF algorithm matlab source code is given, and the algorithm is used for processing target attribute is continuous values of regression problems.By expanding income relief algorithm, can deal with many categories.)

质心定位算法源码，分三种情况考虑，只有锚节点，被定位到的未知节点也作为锚节点，有邻居锚节点的未知节点只利用邻居锚节点进行定位，没有邻居锚节点的未知节点才利用已经定位了的邻居未知节点进行定位。 (Centroid localization algorithm source，Three cases to consider.Only the anchor nodes,unknown nodes to be positioned as anchor nodes,neighbor anchor node of the unknown node using only neighbor anchor node positioning, not unknown neighbor anchor node node neighbor has positioned the unknown node positioning.)

说明：  matlab学习书籍，pdf格式，书名：MATLAB6.5应用接口编程。(matlab learning books, pdf format, title: MATLAB6.5 application interface programming.)

应用了大量互相关检测算法从而得出了同步性能错检率的大小，比较适合刚学习同步算法的人去研究。(Application of a large cross-correlation detection algorithm to arrive at the synchronization performance of the error detection rate of size, more suitable for people just learning to study synchronization algorithm)
