Is it correct that for each row of a matrix after the first, that the hamming distance you are calculating is the distance between that row and the row immediately before it? Why does your output only have 6 rows when the inputs have 7 rows? Jennifer Steven 2017년 6월 12...
To be more specific, the larger variance of two neighboring points, the longer distance between two points. Thus, the difference of neighboring points’ amplitudes can be represented by the edge distance. (7)Improved Permutation Entropy(IPE)[7]:Zhe Chen和Yaan Li等提出的IPE方法,同样考虑到了幅值...

This method provides a straightforward way to assess the correlation between your distance matrices. Here is how you can do it: Convert your distance matrices into vectors excluding the diagonal (zero) elements using the squareform function. Calculate Spearman's rho between these two vector...
