exp10¶
Computes the base 10 exponential of vector elements.
Syntax
Buffer API:
namespace oneapi::mkl::vm { void exp10(queue& exec_queue, int64_t n, buffer<T,1>& a, buffer<T,1>& y, uint64_t mode = mode::not_defined, error_handler<T> errhandler = {} ) }namespace oneapi::mkl::vm { sycl::event exp10(sycl::queue & exec_queue, sycl::buffer<T> & a, oneapi::mkl::slice sa, sycl::buffer<T> & y, oneapi::mkl::slice sy, oneapi::mkl::vm::mode lib_mode = oneapi::mkl::vm::mode::not_defined, oneapi::mkl::vm::error_handler<T> eh = {}); }USM API:
namespace oneapi::mkl::vm { event exp10(queue& exec_queue, int64_t n, T* a, T* y, vector_class<event> const & depends = {}, uint64_t mode = mode::not_defined, error_handler<T> errhandler = {} ) }namespace oneapi::mkl::vm { sycl::event exp10(sycl::queue & exec_queue, T const * a, oneapi::mkl::slice sa, T * y, oneapi::mkl::slice sy, sycl::vector_class<cl::sycl::event> const & depends = {}, oneapi::mkl::vm::mode lib_mode = oneapi::mkl::vm::mode::not_defined, oneapi::mkl::vm::error_handler<T> eh = {}); }

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 sizen
.- sa
Slice selector for
a
. See Data Types for a description of the oneMKL slice type.- sy
Slice selector for
y
. See Data Types for a description of the oneMKL slice type.- 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
mode::not_defined
.- errhandler
Sets local error handling mode for this function call. See the create_error_handler function for arguments and their descriptions. This is an optional parameter. The local error handler is disabled by default.
