Name: gaussf2

Generic parameterized Gauss function with 2 independent variables

[ z:float ] = gaussf2
x:float
y:float
pa:(float,'b,'c) Matrix.t

with the parameter vector:
p.{1} -> z 0
p.{2} -> z m
p.{3} -> sig x
p.{4} -> x 0
p.{5} -> sig y
p.{6} -> y 0

and
F(x,y) = z 0 + z m *exp[ -(
(1/(2*sig x 2 )*(x-x 0 ) 2 ) +
(1/(2*sig y 2 )*(y-y 0 ) 2 ) ]
