SYNOPSIS
Functions/Subroutinesdouble precision function dsdot (N, SX, INCX, SY, INCY)
DSDOT
Function/Subroutine Documentation
double precision function dsdot (integer N, real, dimension(*) SX, integer INCX, real, dimension(*) SY, integer INCY)DSDOT Purpose: Compute the inner product of two vectors with extended
precision 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.Parameters: N N is INTEGER
number of elements in input vector(s)
SX SX is REAL array, dimension(N)
single precision vector with N elements
INCX INCX is INTEGER
storage spacing between elements of SX
SY SY is REAL array, dimension(N)
single precision vector with N elements
INCY INCY is INTEGER
storage spacing between elements of SYReturns: DSDOT DSDOT is DOUBLE PRECISION
