Description | The relative deviation (in absolute terms) between corresponding vectors X and Y is calculated as
reldev = |Xi − Xi | / max( |Xi|, |Yi| )
and the largest reldev encountered is returned.
If both Xi and Yi are zero, reldev is taken as zero, too (thus avoiding an undefined 0/0 situation). |
|
|
Return value | maximum relative deviation encountered. |
