BruteSearch
K-nearest neighbors 搜索 聚类时经常使用的一种方法 国外网站转载( The following utilities are provided:
- Nearest neighbor
- K-Nearest neighbors
- Radius Search
They al supports N-dimensions and work on double, it is possible to choose if return the distances.
Here is a time comparison with a vectrized m-code:
N=1000000 number of reference points
Nq=100 number of query points
dim=3 dimension of points
k=3 number of neighbor

Output:

人脸库代码
说明: 资料为基于BP基于BP神经网络的人脸识别源码(matlab),是课程设计做的一个课题,效果还不错,配备有测试显示界面,比较直观!(The data is the source code of face recognition based on BP neural network (matlab), which is a subject of curriculum design. The effect is good, equipped with test display interface, which is more intuitive!)

该代码是用matalb实现的八皇后源代码,具体功能:可以用鼠标操作,共64个格子,用鼠标点击其中一个方块,其对角线和同一行列的格子都会变成红色,将为不可点击的状态,其中还有定时程序,显示出实现八皇后所用的时间,若实现了就会停止计时,若没有将会一直计时。可以实现重新开游戏功能和退出游戏功能。(The code is matalb Queen' s source code to achieve the eight specific functions: You can use the mouse, a total of 64 grid, right click on a box, the diagonal and the same ranks of the grid will become red, will not Click the state in which there are regular procedures to achieve 8 shows the time used by the Queen, if realized would stop the clock, if not will always be time. Can achieve re-open the game out of the game features and functionality.)
