sb_disjm_i(3PI) Sun Interval Performance Library sb_disjm_i(3PI)NAMEsb_disjm_i - If two interval matrices are dijoint.
DESCRIPTION
TRUE if A IS_DISJOINT with B
The function SB_DISJM_I checks if two symmetric band interval matrices
A and B are disjoint. A IS_DISJOINT with B if and only if Aij IS_DIS‐
JOINT with Bij for some entry of A and B. Matrices A and B have the
same storage format. The routine returns .FALSE. if N is equal to zero
or P is less than zero.
SYNOPSIS
LOGICAL FUNCTION SB_DISJM_I( A, B [, UPLO] )
INTERVAL, INTENT(IN) :: A(:,:), B(:,:)
TYPE(blas_uplo_type), INTENT(IN), OPTIONAL :: UPLO
where
A and B 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.
B (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 or B is unallocated array
blas_error_shape
shape(A) /= shape(B)
