amin_val_i(3PI) Sun Interval Performance Library amin_val_i(3PI)NAMEamin_val_i - Min absolute value and location.
DESCRIPTION
The routine AMIN_VAL_I finds the index of the minimum absolute value
component of an interval vector X. Minimum absolute value component
is defined as follows: the absolute value of the lower or upper bound
of the component is the smallest among the absolute values of the lower
and upper bounds of all components of the interval vector. When the
value of the N argument is equal to zero, the routine should initialize
the output K to negative one or zero, and R to zero. If X contains
some minimal components, then the routine returns smallest index.
SYNOPSIS
SUBROUTINE AMIN_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 minimal component, the result
of AMIN_VAL_I. If there are some minimal components
in the X, K is the smallest index.
R (output)
On exit, R = minimum of Xi absolute value, the result
of AMIN_VAL_I.
ERRORS
blas_error_alloc
X is unallocated array
