The given square matrix A can becomes a singular matrix M by adding any matrix D with multiplier s. That is,
M = A + D*s,
where s is to be determined, so that M is singular. The scalar s is picked as maximum absolute value among the computed non-zero scalers. If A is singular, then s is zero regardless of D.
