vscbrt, vdcbrt The cube root of the elements of a vector
Name vscbrt, vdcbrt
The cube root of the elements of a vector
Purpose vscbrt and vdcbrt calculate the cube root of vector elements:
y(i) = cbrt(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 vscbrt(n, a, y)
INTEGER, INTENT(IN) :: n
REAL (KIND=4), DIMENSION(n), INTENT(IN) :: a
REAL (KIND=4), DIMENSION(n), INTENT(OUT):: y
SUBROUTINE vdcbrt(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.
