Function Documentation

int32_t vec_min_maxi16	(	const int16_t	x[],
		int	n,
		int16_t	out[]
	)

Find the minimum and maximum values in a vector.

Parameters:

	x	The vector to be searched.
	n	The number of elements in the vetor.
	result	A two element vector. The first will receive the maximum. The second will receive thw minimum. This parameter may be set to NULL.

Returns:

The absolute maximum value. Since the range of negative numbers exceeds the range of positive one, the returned integer is longer than the ones being searched.
