SYNOPSIS

SUBROUTINE MAX(X,N,Iwrite,Xmax)

       REAL(kind=wp) :: X(:) , Xmax
       INTEGER :: Iwrite , N

DESCRIPTION

MAX(3f) computes the sample maximum of the data in the input vector x.

INPUT ARGUMENTS

X The vector of (unsorted or sorted) observations.

N The integer number of observations in the vector X.

IWRITE An integer flag code which (if set to 0) will suppress the printing of the sample maximum as it is computed; or (if set to some integer value not equal to 0), like, say, 1) will cause the printing of the sample maximum at the time it is computed.

OUTPUT ARGUMENTS

XMAX The value of the computed sample maximum.

EXAMPLES

Sample program:

   program demo_max
   !use M_datapac, only : max, label
   use M_datapac, only : intel_max=>max, label !  ifort (IFORT) 2021.3.0 20210609 bug

   implicit none
   real :: xmax
      call label(’max’)
      call intel_max([-100.0, 200.0, 0.0, 400.0, -200.0],5,1,xmax)
      !call max([-100.0, 200.0, 0.0, 400.0, -200.0],5,1,xmax)
      write(*,*)xmax
   end program demo_max

Results:

THE MAXIMUM OF THE SET OF 5 OBSERVATIONS IS 0.40000000E+03 400.000000
