tr_interm_i(3PI) Sun Interval Performance Library tr_interm_i(3PI)NAMEtr_interm_i - Intersection of two interval matrices.
DESCRIPTION
The routine TR_INTERM_I finds elementwise intersection of two triangu‐
lar interval matrices A and B. Matrices A and B have the same storage
format. The routine returns immediately if N is equal to zero.
SYNOPSIS
SUBROUTINE TR_INTERM_I( A, B [, UPLO] [, DIAG] )
INTERVAL, INTENT(IN) :: A(:,:)
INTERVAL, INTENT(INOUT) :: B(:,:)
TYPE(blas_uplo_type), INTENT(IN), OPTIONAL :: UPLO
TYPE(blas_diag_type), INTENT(IN), OPTIONAL :: DIAG
where
A and B have shape (N,N).
ARGUMENTS
A (input)
Array of DIMENSION (N,N).
Unchanged on exit.
B (input/output)
Array of DIMENSION (N,N).
On exit, contains elementwise intersection
of A and B.
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.
DIAG (input)
Scalar element.
Specifies whether or not the matrix operand
has unit diagonal entries.
Possible values:
DIAG = blas_non_unit_diag (default)
DIAG = blas_unit_diag
Unchanged on exit.
ERRORS
blas_error_alloc
A or B is unallocated array
blas_error_shape
shape(A) /= shape(B)
