 Find the minimum and maximum values in a vector.

Detailed Description


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.
out A two element vector. The first will receive the maximum. The second will receive the 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.
