sb_interiorm_i(3PI) Sun Interval Performance Library sb_interiorm_i(3PI)NAMEsb_interiorm_i - If an interval matrix is in interior of another.
DESCRIPTION
TRUE if A IS_IN_INTERIOR of B
The function SB_INTERIORM_I checks if an symmetric band interval
matrix A is enclosed in the interior of another symmetric band interval
matrix B. A IS_IN_INTERIOR of B if and only if Aij IS_IN_INTERIOR of
Bij for all entries 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_INTERIORM_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 band 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)
