dotu¶

Computes the dot product of two complex vectors.

dotu supports the following precisions.

T

std::complex<float>

std::complex<double>

Description

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

dotu (Buffer Version)¶

Syntax

void onemkl::blas::dotu(sycl::queue &queue, std::int64_t n, sycl::buffer<T, 1> &x, std::int64_t incx, sycl::buffer<T, 1> &y, std::int64_t incy, sycl::buffer<T, 1> &result)¶

Input Parameters

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

Syntax

sycl::event onemkl::blas::dotu(sycl::queue &queue, std::int64_t n, const T *x, std::int64_t incx, const T *y, std::int64_t incy, T *result, const sycl::vector_class<sycl::event> &dependencies = {})¶

Input Parameters

queue: The queue where the routine should be executed.
n: Number of elements in vectors x and y.
x: 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.
incx: Stride of vector x.
y: 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.
incy: Stride of vector y.
dependencies: List of events to wait for before starting computation, if any. If omitted, defaults to no dependencies.

Output Parameters

Return Values

Output event to wait on to ensure computation is complete.
