An array
in which to return the co-efficients of the linear
approximation to the specified transformation. This array should
have at least "( Nin
1 )
Nout", elements. The first Nout elements
hold the constant offsets for the transformation outputs. The
remaining elements hold the gradients. So if the Mapping has 2 inputs
and 3 outputs the linear approximation to the forward transformation
is:
X_out = fit(1)
fit(4)
X_in
fit(5)
Y_in
Y_out = fit(2)
fit(6)
X_in
fit(7)
Y_in
Z_out = fit(3)
fit(8)
X_in
fit(9)
Y_in
