stdlib_sdsdot Function
public pure function stdlib_sdsdot(n, sb, sx, incx, sy, incy)
Compute the inner product of two vectors with extended precision accumulation. Returns S.P. result with dot product accumulated in D.P. SDSDOT = SB + sum for I = 0 to N-1 of SX(LX+IINCX)SY(LY+IINCY), where LX = 1 if INCX >= 0, else LX = 1+(1-N)INCX, and LY is defined in a similar way using INCY.
