Creates an empty descriptor for the templated precision and forward domain.

Syntax

onemkl::dft::Descriptor<PRECISION, DOMAIN> descriptor

Include Files

• mkl_dfti_sycl.hpp

Description

This constructor initializes members to default values and does not throw exceptions. Note that the precision and domain are determined via templating.

Template Parameters

Name	Type	Description
PRECISION	onemkl::dft::Precision	onemkl::dft::Precision::SINGLE or onemkl::dft::Precision::DOUBLE are supported precisions. Double precision has limited GPU support and full CPU and Host support.
DOMAIN	onemkl::dft::Domain	onemkl::dft::Domain::REAL or onemkl::dft::Domain::COMPLEX are supported forward domains.
