virtual void DiagRecipScale ( const HCL_Vector_d & x, double tol=0.0)

- matrix division by diag(x)

Documentation

- matrix division by diag(x). Safeguarded against overflow - if tol is less that the smallest safe divisor sfmin as defined by LAPACK::[SD]LAMCH, then tol is replaced by sfmin - thus the default is tol=0.0, which effectively means tol=sfmin.
