gb_interm_i(3PI) Sun Interval Performance Library gb_interm_i(3PI)NAMEgb_interm_i - Intersection of two interval matrices.
DESCRIPTION
The routine GB_INTERM_I finds elementwise intersection of two general
band interval matrices A and B. Matrices A and B 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_INTERM_I( A, M, KL, B )
INTERVAL, INTENT(IN) :: A(:,:)
INTERVAL, INTENT(INOUT) :: B(:,:)
INTEGER, INTENT(IN) :: M, KL
where
A and B have shape (L,N) where (L > KL).
ARGUMENTS
A (input)
Array of DIMENSION (L,N) where (L > KL).
Unchanged on exit.
B (input/output)
On entry, array of DIMENSION (L,N)
where (L > KL).
On exit, contains elementwise intersection
of A and B.
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 or B is unallocated array
blas_error_shape
shape(A) /= shape(B)
