NAMEDSDOT - accumulation and result
SYNOPSISDOUBLE PRECISION  FUNCTION DSDOT(N,SX,INCX,SY,INCY)  INTEGER INCX,INCY,N  REAL SX(*),SY(*)
PURPOSEprecision accumulation and result. Returns D.P. dot product accumulated in D.P., for S.P. SX and SY DSDOT = sum for I = 0 to N-1 of SX(LX+I*INCX) * SY(LY+I*INCY), where LX = 1 if INCX .GE. 0, else LX = 1+(1-N)*INCX, and LY is defined in a similar way using INCY.
ARGUMENTSN (input) INTEGER  number of elements in input vector(s) SX (input) REAL array, dimension(N)  single precision vector with N elements INCX (input) INTEGER  storage spacing between elements of SX SY (input) REAL array, dimension(N)  single precision vector with N elements INCY (input) INTEGER  storage spacing between elements of SY DSDOT (output) DOUBLE PRECISION  DSDOT double precision dot product (zero if N.LE.0)
