void	axpby (const rtype a_host, const State &x, const rtype b, const State &y, const rtype *a_device)
	y = a * x + b * y, on both blocks of the state.
void	lerp (const rtype a, const State &x, const State &y)
	y = (1 - a) y + a x as y + a (x - y), on both blocks of the state: unlike axpby with rounded weights a and 1 - a, it leaves y unchanged where x == y.

Function Documentation

axpby()

void axpby	(	const rtype	a,
		const State &	x,
		const rtype	b,
		const State &	y,
		const rtype *	a_device = nullptr
	)

y = a * x + b * y, on both blocks of the state.

y = a x + b y, with a read from device memory instead when a_device is given (graph-captured steps, whose dt lives on the device).

lerp()

void lerp	(	const rtype	a,
		const State &	x,
		const State &	y
	)

y = (1 - a) y + a x as y + a (x - y), on both blocks of the state: unlike axpby with rounded weights a and 1 - a, it leaves y unchanged where x == y.
