-*DECK DDOT
-      DOUBLE PRECISION FUNCTION DDOT (N, DX, INCX, DY, INCY)
-C***BEGIN PROLOGUE  DDOT
-C***PURPOSE  Compute the inner product of two vectors.
-C***LIBRARY   SLATEC (BLAS)
-C***CATEGORY  D1A4
-C***TYPE      DOUBLE PRECISION (SDOT-S, DDOT-D, CDOTU-C)
-C***KEYWORDS  BLAS, INNER PRODUCT, LINEAR ALGEBRA, VECTOR
-C***AUTHOR  Lawson, C. L., (JPL)
-C           Hanson, R. J., (SNLA)
-C           Kincaid, D. R., (U. of Texas)

-C***DESCRIPTION
-C
-C                B L A S  Subprogram
-C    Description of Parameters
-C
-C     --Input--
-C        N  number of elements in input vector(s)
-C       DX  double precision vector with N elements
-C     INCX  storage spacing between elements of DX
-C       DY  double precision vector with N elements
-C     INCY  storage spacing between elements of DY
-C
-C     --Output--
-C     DDOT  double precision dot product (zero if N .LE. 0)
-C
-C     Returns the dot product of double precision DX and DY.
-C     DDOT = sum for I = 0 to N-1 of  DX(LX+I*INCX) * DY(LY+I*INCY),
-C     where LX = 1 if INCX .GE. 0, else LX = 1+(1-N)*INCX, and LY is
-C     defined in a similar way using INCY.
