[163] | 7 | ; calculate the norm of a field of vectors, then make a possible average. |

[142] | 8 | ; Comment 1: The field of vector can be, 2d:xy, 3d: xyz or xyt, |

| 9 | ; 4d: xyzt |
---|
| 10 | ; Comment 2: |
---|
[163] | 11 | ; The calculation of the norm is made before the possible spatial or |
---|
| 12 | ; temporal average because the average of the norm is not equal to the |
