void stan::math::internal::copy_compute_s2	(	Output &&	output,
		Input &&	input
	)

inline

Copies the adjoints from the input to the output, scaling them by 0.5.

Template Parameters

ZeroInput	If true, the adjoints of the input will be set to zero
Output	A tuple or type where all scalar types are `arithmetic` types
Input	A tuple or type where all scalar types are `var` types

Parameters

output	The output to which the adjoints will be added
input	The input from which the adjoints will be collected
