Gauss-Newton method -- exponential fit

Here the residual is : F(x;t_i) = a₀ + a₁*exp(b₁*t_i) + .... + a_n*exp(b_n*t_i) - y_i

Please choose the number of exponential terms
n = Important: n <= 4 !

Specify the original coefficients, 2*n+1 numbers, in this textfield.
The coefficients must be given in the order x = a₀,a₁,b₁, ... , a_n,b_n.

x=	1,1,-1,-4,-2

Specify the interval for the variable t:

a=

b=

Specify the number m of data points:

m=

Important: 2n+1 <= m <= 200 !

Please specify the errorlevel here:

level=

Important: 0 <= level <= 1
