| Description | The absolute values of all elements of a vector are compared and the largest returned. For complex numbers, the magnitudes of the elements are compared and the largest returned. The index of this maximum is stored at the address given by Ind. In case of more than one element with the same maximum value, the lowest index is chosen. |
|
|
| Return value | maximum absolute value encountered. |
