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

NAME
       gemv_i -	 General interval matrix and vector multiplication.

DESCRIPTION
		 Y = ALPHA * A * X + BETA * Y
		 or
		 Y = ALPHA * A_TRANSPOSED * X + BETA * Y
       The  routine GEMV_I multiplies  the interval vector X by general inter‐
       val matrix A or its transpose, scales the resulting interval vector and
       adds  it	 to the scaled interval vector operand Y.  The routine returns
       immediately if N or M is equal to zero.

SYNOPSIS
       SUBROUTINE GEMV_I( A, X, Y [, TRANSA] [, ALPHA] [, BETA] )
       INTERVAL, INTENT(IN) :: A(:,:), X(:)
       INTERVAL, INTENT(INOUT) :: Y(:)
       TYPE(blas_trans_type), INTENT(IN), OPTIONAL :: TRANSA
       INTERVAL, INTENT(IN), OPTIONAL :: ALPHA, BETA
	where
       A has shape (M,N),
       X has shape N and Y has shape M if TRANSA = blas_no_trans (the default)
       X has shape M and Y has shape N if TRANSA /= blas_no_trans

ARGUMENTS
       A (input)
		      Array of DIMENSION (M,N).
		      Unchanged on exit.
       X (input)
		      Array of DIMENSION N if TRANSA = blas_no_trans
		      (the default) or
		      array of DIMENSION M if TRANSA /= blas_no_trans.
		      Unchanged on exit.
       Y (input/output)
		      On entry,
		      array of DIMENSION M if TRANSA = blas_no_trans
		      (the default) or
		      array of DIMENSION N if TRANSA /= blas_no_trans.
		      On exit,
		      if TRANSA = blas_no_trans (the default):
		      Y = ALPHA * A * X + BETA * Y or
		      if TRANSA /= blas_no_trans:
		      Y = ALPHA * A_TRANSPOSED * X + BETA * Y
       TRANSA (input)
		      On entry, TRANSA specifies the matrix A transpose.
		      Possible values:
		      TRANSA = blas_no_trans (the default)
		      TRANSA = blas_trans
		      Unchanged on exit.
       ALPHA (input)
		      On  entry,  ALPHA	 specifies  the	 scalar	  ALPHA.
		      Default value is ALPHA = [1,1].
		      Unchanged on exit.
       BETA (input)
		      On  entry,  BETA	specifies  the	scalar	 BETA.
		      Default value is BETA = [0,0].
		      Unchanged on exit.

ERRORS
       blas_error_alloc
		 A, X or Y is unallocated array

       blas_error_shape
		 A, X or Y has unappropriate shape
