sb_supm_i(3PI) Sun Interval Performance Library sb_supm_i(3PI)NAMEsb_supm_i - Right endpoint of an interval matrix.
DESCRIPTION
C = SUP(A)
The routine SB_SUPM_I finds the real matrix C such that
Cij = SUP(Aij) for all symmetric band interval matrix A entries. The
routine returns immediately if N is equal to zero or P is less than
zero.
SYNOPSIS
SUBROUTINE SB_SUPM_I( A, C [, UPLO] )
INTERVAL, INTENT(IN) :: A(:,:)
REAL, INTENT(OUT) :: C(:,:)
TYPE(blas_uplo_type), INTENT(IN), OPTIONAL :: UPLO
where
A and C have shape (P+1,N) where P = band width.
ARGUMENTS
A (input)
Array of DIMENSION (P+1,N) where P = band width.
Unchanged on exit.
C (output)
Array of DIMENSION (P+1,N) where P = band width.
On exit, contains SUP(Aij) for all A entries.
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 or C is unallocated array
blas_error_shape
shape(A) /= shape(C)
