Parameters

[out]	out	is the output containing elements of a when cond is true else elements from b
[in]	cond	is the conditional array
[in]	a	is the array containing elements from the true part of the condition
[in]	b	is the array containing elements from the false part of the condition

AFAPI af_err af_select_scalar_l	(	af_array *	out,
		const af_array	cond,

Parameters

[out]	out	is the output containing elements of a when cond is true else elements from b
[in]	cond	is the conditional array
[in]	a	is a scalar assigned to out when cond is true
[in]	b	is the array containing elements from the false part of the condition

AFAPI af_err af_select_scalar_r	(	af_array *	out,
		const af_array	cond,
