double simplex	(	double(*)(double *)	_fun,
		int	parNr,
		double *	par,
		double *	delta,
		double	maxerr,
		int	maxiter
	)

Simplex function minimization routine. Note that if any constraints are required for the parameter values they must be set in the function.

Returns:

Function returns the least calculated value of func.

Parameters:

_fun	Pointer to the function to be minimized. It must be defined in main program as: double func(double *p); where p is the parameter array.
parNr	The number of unknown parameters
par	This double array contains the minimized parameters. Initial values must be set.
delta	This double array contains the initial changes to parameters. To fix a parameter, set the corresponding delta to 0.
maxerr	Maximal error allowed (stopping rule #1)
maxiter	Maximal nr of iterations allowed (stopping rule #2)
