dotu

Computes the dot product of two complex vectors.

Syntax

void dotu(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, 1> &result)

dotu 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 dotu routines perform a dot product between two complex vectors:

image0

Input Parameters

exec_queue

The queue where the routine should be executed.

n

Number of elements in vectors x and y.

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(incy)). See Matrix and Vector Storage for more details.

incy

Stride of vector y.

Output Parameters

result

Buffer where the result (a scalar) is stored.
