Computes the "minimal work" distance between two weighted point configurations base on the papers "EMD-L1: An efficient and Robust Algorithm for comparing histogram-based descriptors", by Haibin Ling and Kazunori Okuda; and "The Earth Mover's Distance is the Mallows Distance: Some Insights from Statistics", by Elizaveta Levina and Peter Bickel.

引数

signature1	First signature, a single column floating-point matrix. Each row is the value of the histogram in each bin.
signature2	Second signature of the same format and size as signature1.
