Function Documentation

af_diff2()

AFAPI af_err af_diff2	(	af_array *	out,
		const af_array	in,
		const int	dim
	)

C Interface to calculate the second order difference in an array over a given dimension.

Parameters

[out]	out	second order numerical difference
[in]	in	input array
[in]	dim	dimension along which the difference occurs

Returns

AF_SUCCESS, if function returns successfully, else an af_err code is given

diff2()

AFAPI array diff2	(	const array &	in,
		const int	dim = 0
	)

C++ Interface to calculate the second order difference in an array over a given dimension.

Parameters

[in]	in	input array
[in]	dim	dimension along which the difference occurs, 0 denotes the first non-singleton dimension

Returns

second order numerical difference
