amax_val_i(3PI) Sun Interval Performance Library amax_val_i(3PI)NAMEamax_val_i - Max absolute value and location.
DESCRIPTION
The routine AMAX_VAL_I finds the index of the maximum absolute value
component of an interval vector X. Maximum absolute value component
is defined as follows: the absolute value of the lower or upper bound
of the component has the largest value among the absolute values of the
lower and upper bounds of all components of the interval vector. When
the value of the N is equal to zero, the routine should initialize the
output K to negative one or zero, and R to zero.
SYNOPSIS
SUBROUTINE AMAX_VAL_I( X, K, R )
INTERVAL, INTENT(IN) :: X(:)
INTEGER, INTENT(OUT) :: K
REAL, INTENT(OUT) :: R
where
X has shape (N).
ARGUMENTS
X (input)
Array of DIMENSION N.
Unchanged on exit.
K (output)
On exit, K = index of maximal component, the result
of AMAX_VAL_I. If there are some maximal components
in the X, K is the smallest index.
R (output)
On exit, R = maximum of Xi absolute value, the result
of AMAX_VAL_I.
ERRORS
blas_error_alloc
X is unallocated array
