dotc¶
Computes the dot
product of two complex vectors, conjugating the first
vector.
Description¶
The dotc
routines perform a dot product between two complex vectors, conjugating the first of them:
API¶
Syntax¶
namespace oneapi::mkl::blas::column_major {
void dotc(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)
}
namespace oneapi::mkl::blas::row_major {
void dotc(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¶
- exec_queue
The queue where the routine should be executed.
- n
The number of elements in vectors
x
andy
.- x
Buffer holding input vector
x
. The buffer must be of size at least (1 + (n
- 1)*abs(incx
)). See Matrix 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 Storage for more details.- incy
The stride of vector
y
.
Output Parameters¶
- result
The buffer where the result (a scalar) is stored.
