::
reverse(self, int nadj) -> Function
Get a function that calculates nadj adjoint derivatives.
::
Returns a function with <tt>n_in + n_out + n_out</tt> inputs and <tt>n_in</tt> outputs. The first <tt>n_in</tt> inputs correspond to nondifferentiated inputs. The next <tt>n_out</tt> inputs correspond to nondifferentiated outputs. and the last <tt>n_out</tt> inputs correspond to adjoint seeds, stacked horizontally The <tt>n_in</tt> outputs correspond to adjoint sensitivities, stacked horizontally. * <tt>(n_in = n_in(), n_out = n_out())</tt> <tt>(n_in = n_in(), n_out = n_out())</tt> The functions returned are cached, meaning that if called multiple timed with the same value, then multiple references to the same function will be returned.
