Computes the dot product of two real vectors.
void dot(queue &exec_queue, std::int64_t n, buffer<T,1> &x, std::int64_t incx, buffer<T,1> &y, std::int64_t incy, buffer<T_res,1> &result);
dot supports the following precisions and devices.
T | T_res | Devices Supported |
---|---|---|
float | float | Host, CPU, and GPU |
double | double | Host, CPU, and GPU |
float | double | Host, CPU, and GPU |
The dot routines perform a dot product between two vectors:
For the mixed precision version (inputs are float while result is double), the dot product is computed with double precision.
The queue where the routine should be executed.
Number of elements in vectors x and y.
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.
Stride of vector x.
Buffer holding input vector y. The buffer must be of size at least (1 + (n – 1)*abs(incy)). See Matrix and Vector Storage for more details.
Stride of vector y.
Buffer where the result (a scalar) will be stored.
