dotc

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

Syntax

void dotc(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)

dotc supports the following precisions and devices:

T

Devices Supported

Description

image0

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

Input Parameters

exec_queue

The queue where the routine should be executed.

n

The 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

The 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

The stride of vector y.

Output Parameters

result

The buffer where the result (a scalar) is stored.
