atol

The absolute tolerance (default test) or A tolerance (Fong-Saunders test).

Declaration

var atol: Double

Discussion

In the Fong and Saunders case, this value holds an estimate of the relative error in the data defining the matrix A. For example, if A is accurate to about six digits, set atol = 1.0e-6.
