sdsdot¶
Computes a vector-vector dot product with double precision.
Syntax
-
void
sdsdot(queue &exec_queue, std::int64_t n, float sb, buffer<float, 1> &x, std::int64_t incx, buffer<float, 1> &y, std::int64_t incy, buffer<float, 1> &result)¶
sdsdot supports the Host, CPU, and GPU devices.
Description
The sdsdot routines perform a dot product between two vectors with double precision:
Input Parameters
- exec_queue
The queue where the routine should be executed.
- n
Number of elements in vectors
xandy.- sb
Single precision scalar to be added to the dot product.
- x
Buffer holding input vector
x. The buffer must be of size at least (1 + (n- 1)*abs(incx)). See Matrix and Vector Storage for more details.- incx
Stride of vector x.
- y
Buffer holding input vector
y. The buffer must be of size at least (1 + (n- 1)*abs(incxy)). See Matrix and Vector Storage for more details.- incy
Stride of vector y.
Output Parameters
- result
Buffer where the result (a scalar) will be stored. If
n< 0 the result issb.
