		int	use_hessvec )

inline

A constructor generating data.

Given thermal voltage, minimum and maximum values of source voltages and a step size, values of Is and Rs generates vector of source voltages and solves nonlinear diode equation to populate the vector of measured currents, which is later used as data. If noise is nonzero, adds random perturbation to data on the order of the magnitude of the components. Sets the flag to use Lambert-W function or Newton's method to solve circuit. Sets the flags to use adjoint gradient computation and one of three Hessian-vector implementations.

Lambert-W function for diodes.

Function : DeviceSupport::lambertw Purpose : provides a lambert-w function for diodes and BJT's. Special Notes :

Purpose. Evaluate principal branch of Lambert W function at x.

w = w(x) is the value of Lambert's function. ierr = 0 indicates a safe return. ierr = 1 if x is not in the domain. ierr = 2 if the computer arithmetic contains a bug. xi may be disregarded (it is the error).
