sb_copy_i(3PI) Sun Interval Performance Library sb_copy_i(3PI)NAMEsb_copy_i - Symmetric band interval matrix copy.
DESCRIPTION
B = COPY of A
The routine SB_COPY_I copies a symmetric band interval matrix A and
stores the result in an interval matrix B. Matrices A and B have the
same storage format. The routine returns immediately if N is equal to
zero or K is less than zero.
SYNOPSIS
SUBROUTINE SB_COPY_I( A, B [, UPLO] )
INTERVAL, INTENT(IN) :: A(:,:)
INTERVAL, INTENT(OUT) :: B(:,:)
TYPE(blas_uplo_type), INTENT(IN), OPTIONAL :: UPLO
where
A and B have shape (K+1,N) where K = band_width.
ARGUMENTS
A (input)
On entry, A is array of DIMENSION (K+1,N)
where K = band_width.
Unchanged on exit.
B (output)
On entry, B is array of DIMENSION (K+1,N)
where K = band_width.
On exit, B is the copy of array A.
UPLO(input)
Scalar element.
Specifies if the matrix operand is an upper or
lower tringular part of the symmetric 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
A or B has unappropriate shape
