matrix on each base. The larger the eigenvalues, the greater the variance of the matrix on the corresponding eigenvector, the greater the power and the more information. However, eigenvalue decomposition also has a lot of limitations, such as the transformation of the matrix must be a square.In machine learning feature extraction, the meaning is that the maximum eigenvalue corresponding to the direction of the eigenvector contains the most information, if a certain number of characteristics are

Density Clustering
FPC::d Bscan
FPC::d BscanDbscan Core idea: If a point, within the range of its EPs, is not less than minpts points, then the point is the core point. A cluster is formed between the core and its neighbors within the EPS range. In a cluster, if more than one point appears to be the core point, the clusters centered on these core points are merged. Note that the parameter

a+i point to, that is, a[i], and pointer variables that point to the array can also be marked with the same value as * (P[i). So, in the actual use of this function, if you encounter an array as a parameter, you can call the first element address of the array as the argument value of the function.
