I'm trying to create a clustering algorithm using a particular approach:
First, I want to use the mahalanobis distance to compute distance between observations (I do have the ML and optimization toolbox).
Then, my idea is to use the linkage function to create a tree. But the issue that I cannot find an answer for is that I want to compute distance between nodes using a distance that I created, which is different from the mahalanobis distance. The second distance is only working between clusters.
Thanks for your answers
