I’m trying to learn how to use autodifferentiation for the first time since that came up in something else. What am I doing wrong? using ForwardDiff f(x) = 2x g = x -> ForwardDiff.gradient(f, x) g(2) # DimensionMismatch("gradient(f, x) expects that x is an array. Perhaps you meant derivative(f, x)?…

How to use ForwardDiff?

you probably want the derívative, rather than the gradient.
