gb_lrscale_i(3PI)      Sun Interval Performance Library	     gb_lrscale_i(3PI)

NAME
       gb_lrscale_i - Two-sided diagonal scaling.

DESCRIPTION
		      A = DL * A * DR  with DL, DR diagonal
       The routine GB_LRSCALE_I scales a general band interval matrix A on the
       left side by an interval diagonal matrix DL and on the right side by  a
       interval	 diagonal matrix DR.  This routine returns immediately if M or
       N is equal to zero or KL is less than zero.

SYNOPSIS
       SUBROUTINE GB_LRSCALE_I( DL, DR, A, M, KL )
       INTERVAL, INTENT(IN)    :: DL(:), DR(:)
       INTERVAL, INTENT(INOUT) :: A(:,:)
       INTEGER, INTENT(IN)     :: M, KL
	   where
       DL has shape (M).
       DR has shape (N).
       A has shape (L,N), where L > KL.

ARGUMENTS
       DL (input)
		      Array of DIMENSION (M).
		      Unchanged on exit.
       DR (input)
		      Array of DIMENSION (N).
		      Unchanged on exit.
       A (input/output)
		      On entry, array of DIMENSION (L,N), where L > KL.
		      On exit, A = DL * A * DR.
       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, DL or DR is unallocated array

       blas_error_shape
		 A, DL or DR has unappropriate shape
