| 14 | * | ||
| 15 | * Selects minimum value from each entry between bVector and aVector | ||
| 16 | * and store their results in the cVector. | ||
| 17 | * | ||
| 18 | * c[i] = min(a[i], b[i]) | ||
| 19 | * | ||
| 20 | * <b>Dispatcher Prototype</b> | ||

| 25 | * | ||
| 26 | * \b Inputs | ||
| 27 | * \li aVector: First input vector. | ||
| 28 | * \li bVector: Second input vector. | ||

| 30 | * | ||
| 31 | * \b Outputs | ||
| 32 | * \li cVector: The output vector. | ||
