fmin

Returns the smaller of each pair of elements of the two vector arguments.

Syntax

Buffer API:

namespace oneapi::mkl::vm {

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

} // namespace oneapi::mkl::vm

USM API:

namespace oneapi::mkl::vm {

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

} // namespace oneapi::mkl::vm

fmin supports the following precisions.

T

float

double

Description

The fmin(a, b) function returns a vector with element values equal to the smaller value from each pair of corresponding elements of the two vectors a and b: if a > bfmin(a, b) returns b, otherwise fmin(a, b) returns a.

Argument 1

Argument 2

Result

Status code

a not NAN

NAN

a

NAN

b not NAN

b

NAN

NAN

The fmin(a, b) 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 1st input vector of size n.

b

The buffer b containing 2nd 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::mkl::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 1st input vector of size n.

b

Pointer b to the 2nd 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::mkl::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).
