sb_emptyelem_i(3PI) Sun Interval Performance Library sb_emptyelem_i(3PI)NAMEsb_emptyelem_i - Empty entry and its location.
DESCRIPTION
K = index of empty entry or K=-1
The routine SB_EMPTYELEM_I checks if an symmetric band interval matrix
A contains an empty interval entry. If A contains empty interval
entries, then the routine returns the smallest offset or index K
(according to the first index) such that Akj = [NaN_empty,NaN_empty].
Otherwise, the routine returns K=-1.
SYNOPSIS
INTERGER FUNCTION SB_EMPTYELEM_I( A [, UPLO] )
INTERVAL, INTENT(IN) :: A(:,:)
TYPE(blas_uplo_type), INTENT(IN), OPTIONAL :: UPLO
where
A has shape (P+1,N) where P = band width.
ARGUMENTS
A (input)
Array of DIMENSION (P+1,N) where P = band width.
Unchanged on exit.
UPLO(input)
Scalar element.
Specifies if the matrix operand is an upper
or lower tringular part of the matrix.
Possible values:
UPLO = blas_upper (default)
UPLO = blas_lower
Unchanged on exit.
ERRORS
blas_error_alloc
A is unallocated array
