RFO regularisation for Newton-Raphson Hessian and gradient pairs.
Syntax
[H,data]=hessreg(spin_system,H,g,data)
Parameters
H - Hessian matrix to be regularised g - gradient computed at the same point as H data - diagnostic data structure
Returns
H - regularised Hessian
data - updated diagnostic data structure with
data.count.rfo incremented by the number
of RFO iterations taken
