Find the dot product of two int16_t vectors, where the first is a circular buffer with an offset for the starting position.
- Parameters
-
x | The first vector. |
y | The first vector. |
n | The number of elements in the vectors. |
pos | The starting position in the x vector. |
- Returns
- The dot product of the two vectors.

Find the dot product of two int16_t vectors.
- Parameters
-
x | The first vector. |
y | The first vector. |
n | The number of elements in the vectors. |
- Returns

int32_t vec_min_maxi16 |
( |
const int16_t | x[], |

int16_t | out[] ) |
Find the minimum and maximum values in an int16_t vector.
- Parameters
-
x | The vector to be searched. |
n | The number of elements in the vector. |
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.
