Update gradient (oLBFGS, SQN, adaQN)

Update the (expected) gradient in an optimizer from this package, after it has been requested by the optimizer (do NOT update it otherwise).

update_gradient(optimizer, gradient)

Arguments

• optimizer: A free-mode optimizer from this package (oLBFGS_free, SQN_free, adaQN_free) which after the last run had requested a new gradient evaluation..
• gradient: The (expected value of the) gradient as evaluated on the values of x that were returned in the request. Must be a numeric vector.
