Chapter 12 VMATH 853
The complimentary error function of the elements of a vector vserfc, vderfc
Name vserfc, vderfc
The complimentary error function of the elements of a vector
Purpose vserfc and vderfc calculate the complimantary error function of vector
elements:
y(i) = 1.0 - erfc(a(i)), for 1 <= i <= n
Usage The Fortran include file math.fi declares interfaces for these subroutines,
suitable for both VMATH and VMATH8. The interfaces are compatible with
Intel’s MKL VML (Vector Math Library).
SUBROUTINE vserfc(n, a, y)
INTEGER, INTENT(IN) :: n
REAL (KIND=4), DIMENSION(n), INTENT(IN) :: a
REAL (KIND=4), DIMENSION(n), INTENT(OUT):: y
SUBROUTINE vderfc(n, a, y)
INTEGER, INTENT(IN) :: n
REAL (KIND=8), DIMENSION(n), INTENT(IN) :: a
REAL (KIND=8), DIMENSION(n), INTENT(OUT):: y
Input n Number of elements to be calculated.
a Array of length at least n, specifying the input vector.
Output y Array of length at least n specifying the output vector.
