[Help-gsl] Help with Geodesic Acceleration

[Hauser Fabian]

Dear whom it may concern,


I want to use the Geodesic Acceleration (GSL V2.2.1) in combination with the 
Levenberg-Marquardt? Algorithm to minimize a 2D Gaussian function. The Problem 
is I have no idea who to develop the formula for f_vv. The source code 
'test_gaussian.c' and the documentation couldn't help me.


Can someone explain me (mathematically) how develop any formal for Geodesic 
Acceleration for this approach?


Thanks in advance,

Fabian Hauser
