Computes the dot product of two complex vectors.
event dotu(queue &exec_queue, std::int64_t n, const T *x, std::int64_t incx, const T *y, std::int64_t incy, T *result, const vector_class<event> &dependencies = {});
The USM version of dotu supports the following precisions and devices.
T | Devices Supported |
---|---|
std::complex<float> | Host, CPU, and GPU |
std::complex<double> | Host, CPU, and GPU |
The dotu routines perform a dot product between two complex vectors:
The queue where the routine should be executed.
Number of elements in vectors x and y.
Pointer to the input vector x. The array holding input vector x must be of size at least (1 + (n - 1)*abs(incx)). See Matrix and Vector Storage for more details.
Stride of vector x.
Pointer to input vector y. The array holding input vector y must be of size at least (1 + (n - 1)*abs(incy)). See Matrix and Vector Storage for more details.
Stride of vector y.
List of events to wait for before starting computation, if any. If omitted, defaults to no dependencies.
Pointer to where the result (a scalar) is stored.
Output event to wait on to ensure computation is complete.
