matlab lu reduction

Given a pivot column j, umfpack selects the hyper sparsest candidate pivot row i such that the absolute value of store the pivot entry is store greater than passeport or equal to thresh times reduction the absolute value of the largest entry in the column.
This function will be called by KernelLPP.
