WebFunction which computes the vector of residuals, with the signature fun(x, *args, **kwargs), i.e., the minimization proceeds with respect to its first argument.The argument x passed to this function is an ndarray of shape (n,) (never a scalar, even for n=1). It must return a 1-d array_like of shape (m,) or a scalar.
