REAL FUNCTION SDSDOT(N,B,X,INCX,Y,INCY) INTEGER N,INCX,INCY REAL B,X(*),Y(*)
The SDSDOT function computes the sum of constant B and dot product of vectors X and Y.
|N||On entry, N specifies the number of elements in X and Y; unchanged on exit.|
|B||Scalar; unchanged on exit.|
|X||Vector of dimension at least (1 + (N-1) * abs(INCX) ); unchanged on exit.|
|INCX||On entry, INCX specifies the increment for the elements of X; INCX must be greater than zero; unchanged on exit.|
|Y||Vector of dimension at least (1 + (N-1) * abs(INCY) ); unchanged on exit.|
|INCY||On entry, INCY specifies the increment for the elements of Y; INCY must be greater than 0; unchanged on exit.|
For values of N <= 0, the subroutine returns immediately.
Computation is performed in double precision.
