Description:

Fits a double gaussian function.

Algorithm: 

	Double gaussian function:

		y = a + b*exp(c*s^2) + d*exp(f*s^2)

		with a = 0

Arguments:

int nnumber of data points.
double* xx array (at least order+1 values).
double* yy array (at least order+1 values).
double* coeffarray in which 5 coefficients are returned
(if NULL,no coefficients returned).

Returns:

double R value.
