{ return ((iy-1)*(2*ix-iy+2))/2; }Takes values in the range [0,1]. Larger values enforce greater stability in the factorization as they insist on larger pivots. Smaller values preserve sparsity at the cost of using smaller pivots.
{ return fCntl[1]; }The factorization will not accept a pivot whose absolute value is less than fCntl[3] as a 1x1 pivot or as the off-diagonal in a 2x2 pivot.
{ fCntl[1] = piv; }
