Dear All, I'm new user of the Mahout library, and I'd like to use it to compute Mahalanobis distances between vectors. Each of my vector is very sparse and big, so I'd like to store all of them in a SparseMatrix object, and then use the Mahalanobis class. The Mahalanobis class requires the covariance matrix, but I do not find any class or method to compute it neither in mahout-core nor in mahout-math.
Please can you help me? Thanks a lot Marco
