Oops. You are right about the if, was a last minute change, my bad.
There are lot's of "modified" lines due to trailing spaces (I use a
trailing space killer on save).
On the help message I meant:
The function handle "f" should be of the form Y = f(X). So it must
accept a vector X and return a vector Y of the same length and
orientation as X.
Then DX = deriv(f,X0), will return a vector DX with the derivatives of
'f' in the points X0 (a vector). By convention I use uppercase single
letters for vectors and matrixes and lowercases for scalars. Hope I
didn't messed it up too much :P
