gb_copy_i(3PI) Sun Interval Performance Library gb_copy_i(3PI)NAMEgb_copy_i - General band interval matrix copy.
DESCRIPTION
B = COPY of A or B = COPY of A_transposed
The routine GB_COPY_I copies a general band interval matrix A (or its
transpose) and stores the result in an interval matrix B. Matrices A
(or A_transposed) and B have the same storage format. This routine
returns immediately if M or N is equal to zero or KL is less than zero.
SYNOPSIS
SUBROUTINE GB_COPY_I( A, M, KL, B [, TRANSA] )
INTERVAL, INTENT(IN) :: A(:,:)
INTERVAL, INTENT(OUT) :: B(:,:)
INTEGER, INTENT(IN) :: KL, M
TYPE(blas_trans_type), INTENT(IN), OPTIONAL :: TRANSA
where
If TRANSA = blas_no_trans (default): A and B have shape (L,N)
where (L > KL).
If TRANSA /= blas_no_trans: A has shape (L,N) and B has shape
(L,M) where (L > KL).
ARGUMENTS
A (input)
On entry, A is array of DIMENSION (M,N).
Unchanged on exit.
B (output)
On entry, B is array of DIMENSION (M,N)
if TRANSA = blas_no_trans (default).
B is array of DIMENSION
(N,M) if TRANSA /= blas_no_trans.
On exit, B is the copy of array A or
A_transposed.
KL (input)
The number of the subdiagonal bands.
Unchanged on exit.
M (input)
Number of rows in the source general matrix.
Unchanged on exit.
TRANSA (input)
Scalar element.
Specifies the matrix A transpose.
Possible values:
TRANSA = blas_no_trans (default)
TRANSA = blas_trans
Unchanged on exit.
ERRORS
blas_error_alloc
A or B is unallocated array
blas_error_shape
A or B has unappropriate shape
