SFSDP is a Matlab package for solving sensor
network localization problems. The
package containsfour functions, SFSDP.m, SFSDPplus.m, generateProblem.m,test_SFDP.m,
andsome numerical examples. The function SFSDP.m
is an Matlab implementation of the semidefinite programming relaxationproposed in the paper  by
Kim, Kojima and Waki for sensor network localization
problems, as a sparse version of the full semidefinite
programming relaxation (FSDP)by Biswas and Ye . To improve the efficiency of FSDP, SFSDP.mexploits the aggregated
and correlative sparsity of a sensor network localization problem.
