Distance Matrix Format (.matrix)

The distance matrix represents the the dissimilarity of all pairs of models in the database. For N models, the matrix is a sequence of N by N floating point numbers in binary format, where the number at position i*N+j represents the distance between models i and j. A value of zero indicates that the descriptors are identical, and larger values indicate greater dissimilarity between the 3D models. All distance values should be positive and can be arbitrarily large.
