gb_constructm_i(3PI) Sun Interval Performance Library gb_constructm_i(3PI)NAMEgb_constructm_i - Constructs an interval matrix from two floating point
matrices.
DESCRIPTION
The routine GB_CONSTRUCTM_I constructs an general band interval
matrix A from two general band floating point matrices B and C such
that all matrix A entries Aij contain the interval
[MIN(Bij,Cij),MAX(Bij,Cij)]. Both floating point matrices B and C have
the same storage format. The routine returns immediately if M or N is
equal to zero or KL is less than zero.
SYNOPSIS
SUBROUTINE GB_CONSTRUCTM_I( A, M, KL, B, C )
INTERVAL, INTENT(OUT) :: A(:,:)
REAL, INTENT(IN) :: B(:,:), C(:,:)
INTEGER, INTENT(IN) :: M, KL
where
A, B and C have shape (L,N) where (L > KL).
ARGUMENTS
A (output)
Array of DIMENSION (L,N) where (L > KL).
On exit, contains [MIN(Bij,Cij),MAX(Bij,Cij)]
for all A entries.
B (input)
Array of DIMENSION (L,N) where (L > KL).
Unchanged on exit.
C (input)
Array of DIMENSION (L,N) where (L > KL).
Unchanged on exit.
M (input)
Number of rows in the source general matrix.
Unchanged on exit.
KL (input)
The number of the subdiagonal bands.
Unchanged on exit.
ERRORS
blas_error_alloc
A, B or C is unallocated array
blas_error_shape
shape(A) /= shape(B) /= shape(C)
