Wasserstein-1 distance
W1_parallel(X, C, set_c)
A Filebacked Big Matrix n x N.
A Filebacked Big Matrix N x l, which stores the Wasserstein distances.
Column index vector. The data vector indices for which the Wasserstein distances are computed.
The Wasserstein-1 distances are computed between the data vectors from set_c and all columns of X.
