conj#

Performs element by element conjugation of the vector.

Syntax

Buffer API:

namespace oneapi::math::vm {

sycl::event conj(
        sycl::queue& exec_queue,
        std::int64_t n,
        sycl::buffer<T,1>& a,
        sycl::buffer<T,1>& y,
        oneapi::math::vm::mode mode = oneapi::math::vm::mode::not_defined);

} // namespace oneapi::math::vm

USM API:

namespace oneapi::math::vm {

sycl::event conj(
        sycl::queue& exec_queue,
        std::int64_t n,
        const T *a,
        T* y,
        std::vector<sycl::event> const & depends = {},
        oneapi::math::vm::mode mode = oneapi::math::vm::mode::not_defined);

} // namespace oneapi::math::vm

conj supports the following precisions.

T
`std::complex<float>`
`std::complex<double>`

Description

The conj function performs element by element conjugation of the vector.

No special values are specified. The conj function does not generate any errors.

Input Parameters

Buffer API:

exec_queue: The queue where the routine should be executed.
n: Specifies the number of elements to be calculated.
a: The buffer a containing input vector of size n.
mode: Overrides the global VM mode setting for this function call. See set_mode function for possible values and their description. This is an optional parameter. The default value is oneapi::math::vm::mode::not_defined.

USM API:

exec_queue: The queue where the routine should be executed.
n: Specifies the number of elements to be calculated.
a: Pointer a to the input vector of size n.
depends: Vector of dependent events (to wait for input data to be ready).
mode: Overrides the global VM mode setting for this function call. See the set_mode function for possible values and their description. This is an optional parameter. The default value is oneapi::math::vm::mode::not_defined.

Output Parameters

Buffer API:

y: The buffer y containing the output vector of size n.

USM API:

y: Pointer y to the output vector of size n.
return value (event): Event, signifying availability of computed output and status code(s).
