NORM2 — Euclidean vector norms#
-
NORM2(ARRAY, DIM)#
Calculates the Euclidean vector norm (L_2 norm) of
ARRAY
along dimensionDIM
.- Parameters
ARRAY – Shall be an array of type
REAL
DIM – (Optional) shall be a scalar of type
INTEGER
with a value in the range from 1 to n, where n equals the rank ofARRAY
.
- Returns
The result is of the same type as
ARRAY
.
- Standard:
Fortran 2008 and later
- Class:
Transformational function
- Syntax:
RESULT = NORM2(ARRAY[, DIM])
- Example:
PROGRAM test_sum REAL :: x(5) = [ real :: 1, 2, 3, 4, 5 ] print *, NORM2(x) ! = sqrt(55.) ~ 7.416 END PROGRAM
