Euclidean Distance Matrix Completion

edmc

edmc(D, method = "dpf", ...)

Arguments

D	An nxn partial-distance matrix to be completed, with unkown entries set to NA.
method	The algorithm to be used to complete the distance matrix D. One of sdp, npf, dpf, snl, or grs
...	The remaining input values required for the completion method specified in method. See details.

Value

The return from edmc depends on the method used. The help pages for each individual method can be consulted for specific output.

Details

Depending on the method called, a number of input values are possible.
