this object is used by the Chv object to implement the
"patch-and-go" strategies, used in specialized optimization
and structural analysis applications.
strategy -- type of patch-and-go strategy
1 -- used with optimization matrices
if ( |a_{i,i}| <= toosmall ) {
set a_{i,i} = 1.0
set offdiagonals = 0.0
}
2 -- used with structural analysis matrices
if ( |a_{i,i}| <= fudge ) {
set a_{i,i} = fudge * max (1, |a_{i,*}|, |a_{*,i}|)
}
toosmall -- measure of smallness for diagonal entry
fudge -- change factor for diagonal entry
fudgeIV -- (optional) stores locations where modifications made
fudgeDV -- (optional) stores modifications

stored in a DV object
