dotc (USM Version)

Computes the dot product of two complex vectors, conjugating the first vector.

Syntax

void dotc(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 dotc supports the following precisions and devices:

T

Devices Supported

std::complex<float>

Host, CPU, and GPU

std::complex<double>

Host, CPU, and GPU

Description

The dotc routines perform a dot product between two complex vectors, conjugating the first of them:

image0

Input Parameters

exec_queue

The queue where the routine should be executed.

n

The number of elements in vectors x and y.

x

Pointer to input vector x. The array holding the input vector x must be of size at least (1 + (n - 1)*abs(incx)). See Matrix and Vector Storage for more details.

incx

The stride of vector x.

y

Pointer to input vector y. The array holding the input vector y must be of size at least (1 + (n - 1)*abs(incy)). See Matrix and Vector Storage for more details..

incy

The stride of vector y.

dependencies

List of events to wait for before starting computation, if any. If omitted, defaults to no dependencies.

Output Parameters

result

The pointer to where the result (a scalar) is stored.

Return Values

Output event to wait on to ensure computation is complete.
